Meet Kelli Dawson, the disturbed 28-year-old woman who was sleeping with Casey Aldridge — when Casey was only 17 — and still sees him, she says.

“I see him all the time, at least once a week,” she tells InTouch.

The pair first met in November 2006, at the home of her sister, Kim Toller. At the time, Casey was already dating Jamie Lynn, but the sexual chemistry between Casey and Kelli was instant. “We were both really attracted to each other,” Kelli reveals. “He totally instigated it and pursued me. His friends would tell me that he liked me, that he thought I was pretty.” The couple saw each other a few times and “kissed randomly,” but it wasn’t really “hot and heavy,” Kelli admits, until the spring of 2007. Though Casey and Jamie Lynn were still involved, Kelli insists, “You never knew if they were broken up or not, because it changed from day to day!”

The pair didn’t bother to hide their relationship. “Kelli and Casey have been a couple on and off for a few years,” confirms Jason Alexander, Britney Spears’ first husband and a native of nearby Kentwood, La. “They were a really tight couple, but I think it was hard for Kelli, having Jamie Lynn in the picture.”

Kelli says she and Casey stopped sleeping together a few months before Jamie Lynn gave birth to their daughter, Maddie. “It just didn’t feel right,” she explains. “He had to deal with the baby coming, and it had to stop.” She says the last time the couple had sex together was in March but “even after we stopped having sex, we would still kiss occasionally.”

Ew, I’m sorry, but if they’ve been together for “a few years,” that means that when they started dating, she was, like, 25 and he was around 16.

Ew, ew, ew, ew.

This girl is so disturbed. What kind of 25-year-old woman wants to date a 16-year-old boy? Not only is it mildly illegal, it’s also really gross and disturbing. I mean, even today, I look at college guys and I’m like, “Ew, they’re so young!” (one exception is Michael Phelps, of course), and at least those guys are LEGAL.

And then to talk about it in front of a national audience???

What do you think InTouch paid her for this interview? $10K? $20K?

Was it worth it, dear?

Us magazine is reporting that JLS’s engagement to supposed baby daddy Casey Aldridge is confirmed … by one of Casey’s cousins.

“He proposed a few days ago, and she accepted,” said cousin Tina Roberts.

Okay, is this really a confirmation? Like, this is Mississippi, right? How many cousins do you think Casey Aldridge has? And couldn’t he be married to one already?

The cousin says she hasn’t seen the ring and didn’t know if the wedding would take place before or after Jamie delivers.

And let’s not forget here that Jamie-Lynn is sixteen years old.

Sixteen!

In California, she wouldn’t even qualify for an unrestricted drivers license!

This rumor’s been going around for awhile, so I’ll pass it on to you guys.

Word on the street is that Casey Aldridge is taking the fall for the Jamie-Lynn Spears pregnancy since he did date her, and, being less than two years older than she is, can’t be held on statutory rape charges. They say he hasn’t even really been dating Jamie-Lynn recently, and that the father is actually a much older exec on her TV show.

Star magazine insists that the teenager may not be the dad - and that Spears’ friends and family think it is an older man who would face statutory rape charges.

Friends have said that Jamie Lynn was no longer even seeing Casey - and family members told Star that they believe the real father is a much older executive at her children’s TV show ‘Zoey 101′.

“Casey is being paid off to be the family’s fall guy while the real father remains unidentified,” Star magazine insists.

They say the real reason is that an older man could be charged with statutory rape if revealed to be the father of an under-aged girl’s baby.

But in Jamie Lynn’s home state of Louisiana, Casey would escape charges because a 16-year-old can legally have sex with someone less than two years older than her. “Conveniently, Casey falls under the bar by just 26 days.

“The man many suspect is the father, however, would face charges and probably prison time if he were to come forward and admit he had sex with her,” Star magazine states.

The magazine quotes “two separate Spears family insiders” who believe the father is someone who works on Jamie Lynn’s kids’ show. “Jamie Lynn has been working on Zoey since she was 13,” one of the sources said. “In Hollywood, little girls grow up fast, and she is no exception.

“With everything that has gone on in her family, she needed someone to look up to.

“But the man she found seems to have completely taken advantage of her.”

Oh, I do hope this is true!!! But there’ll be no way to tell without a DNA test, which I’m sure Jamie won’t get if she’s trying to protect this dude.

The issue of OK! with the JLS interview is finally on stands. Here are some of the highlights.

1) First, she denies she is living with Casey Aldridge:

Are you guys living together?
No, I live with my mom. He lives with his parents. For now, that’s the best thing to do. We need to focus on the baby right now.

2) Casey is 18 years old, not 19. DMV records indicate he was born April 29, 1989. This means he is less than two years older than JLS, and as such will be clear of any statutory rape claims.

3) The two of them met — where else? — in church. The very best place to start on the path to teenage pregnancy.

How long have you and Casey been together?
This Christmas, it’ll be about two and a half years, I think. At first, I was just friends with him; I’ve been friends with him since I was about 14. Then we started dating. I met him at church. He came there with a friend; I came there with a friend. We started talking and then started hanging out.

4) Jamie-Lynn talks more about the pregnancy, claiming Casey was the first person she told:

Who did you call first when your pregnancy was confirmed?
It was probably Casey. It was a shock for both of us, so unexpected. I was in a complete and total shock and so was he.

When did you see him after finding out?
The next day, he wanted to meet me in person to talk about what we had to do. It was something we couldn’t really talk about over the phone. We met and talked about everything and decided what we wanted to do. He was 100 percent supportive, and we figured it out.

Was this planned?
Oh, it was a big shock.

Why did you decide to keep the baby?
I think my whole life I would have to live with knowing what I did or what I didn’t do. I’m trying to do the right thing. I think that this is what is going to make me happy in the end.

Other people your age might not be brave enough to take on this kind of commitment…
Well, I was scared at first. I took the time to think about it for myself, and I though: “What would be right for me?” I’m the one who has to live with it for the rest of my life. I put myself in this position, an adult position, so I have to act like an adult and take responsibility for what I did. I have really become at peace with the whole situation, and I think it’s the right thing for me to do. It’s a personal decision that everyone would have to make for themselves. This one is just right for me….

What was [your mom’s] reaction when you told her you were pregnant?
She didn’t really say anything at first. She just kind of looked at me. It was me and Casey that told her. She didn’t believe us. But then she looked at Casey and he’s always been very straightforward, and then she knew it was real. She was very upset because it wasn’t what she expected at all. A week after, she had time to cope with it and became very supportive.

It doesn’t appear the Casey Aldridge is quite prepared yet to become the next Kevin Federline.

I mean, what the hell would we call him? C-Ald? Case-dridge? No, no, no. None of it works.

The media have descended on his tiny hometown of Gloster, Mississippi, but Casey has been nowhere to be found.

“I don’t think they are ready yet to sit down and talk to the media,” his uncle, a pastor in Gloster, Miss., told The Associated Press by telephone Thursday. “They haven’t gotten their heads together yet … He doesn’t want to say the wrong thing to the media. At the right time he will speak … He is a quiet guy. That is why it is going to be very difficult to corner him until everybody is ready to talk together on the same page. He doesn’t like the limelight. He is going to hide as much as he can.”

The uncle said Casey has gone into hiding for now, and denied reports that his nephew and JLS, who was a guest at Jackson’s home this past Thanksgiving, were no longer together.

“I think they are going to try to stay together,” he said. “They certainly don’t want to part.”

As for marriage?

Jackson said Casey has told family members that “he wants to go ahead and get married as soon as possible.”

He told reporters his nephew briefly attended a junior college in Mississippi but now works for a pipe-laying company in Baton Rouge, La. He attended school at Amite School Center in nearby Liberty, Miss., where he played football and baseball, principal Dan Brewer said.

Awwww.

Hiding from the media? How quaint.

I love this guy already.
