Dude, so how long did it take for this “serious relationship” to fall to pieces? A month? Two?

Sources are reporting that John dumped Jen.

“There’s been a bit of tension for some time,” says a source close to 30-year-old John. “They initially opted for a break, hoping a trial split might make them stronger. Sadly it doesn’t seem to have worked. John took the decision to end things as he felt he just wasn’t ready for the level of commitment that Jennifer deserved.”

Word is that Jen’s already got a new man — some sort of male model. Sigh. Isn’t she bored of the male models yet?

This is a fun little item from Page Six:

JOHN Mayer might have broken Minka Kelly’s heart when he left her for Jennifer Aniston - but he had the decency to call her before the news about them hit the press. A Kelly pal said, “Minka [above] received a call from John prior to the story breaking about his relationship with Jennifer. He apologized to Minka, ‘Sorry, but I’m really in love.’ ” She found that interesting as, “during his relationship with her, John mentioned, ‘I don’t really get this Jennifer Aniston thing.’ ” Mayer’s rep declined to comment.

Well, I’ll tell ya, John Mayer’s getting plenty of Jennifer Aniston’s thing these days.

He’s gonna get bored of her so quick.

On the heels of initial reports that the two were spotted sharing a meal in Miami, we’re now hearing that they later had an intimate dinner that lasted until 1 a.m.

They had a “cozy” dinner at Casa Tua in Miami Beach, and were spotted holding hands as they returned to their hotel.

Damn.

What do we think of this new pairing, kids?

Yup.

I wanna pet that.

Okay, this is a very weird story. I don’t know much about Ricki Lake, but, last I heard, she wasn’t exactly John Mayer’s type. So I’m not sure what to make of this latest bit of gossip.

John Mayer - clearly not thinking of his most recent flings with Minka Kelly or Cameron Diaz - made a beeline for Ricki Lake at the Sunshine Sachs p.r. company’s Christmas party. The two talked about Lake’s new documentary, “The Business of Being Born,” before Mayer confessed, “I’ve had a crush on you for two years.” Helpful publicists then herded the two to a back table, where they exchanged numbers. Lake soon left and went to the Rose Bar, where Mayer texted her throughout the night.

What do you guys think? Is Ricki Lake hot?

In truth, I can’t think of a relationship I care less about right now.

But for those of you who do care, they were spotted on yet another NYC date.

The pair, who were first spotted out together in the city last week, were “all over each other” and “super flirty” at the Bowery Hotel Friday night, an onlooker tells PEOPLE.

Mayer, 29, and Diaz, 34, who sat together on a couch in the back of the patio, “were laughing and talking a lot” as the waitress brought several rounds of drinks, says the source.

Last Tuesday, the pair were spotted having dessert at the French-Vietnamese restaurant Indochine. “It looked like a casual date,” said a source. “She was giggly. She was laughing and seemed happy.”

Asked if the newly-close pair are dating, a source close to Mayer tells PEOPLE, “Yes, it’s definitely true.”

This must be a really weird week for Jessica Simpson. I mean, the naked pictures of Vanessa “Bush” Minnillo hit the web on Friday, so that must have been pretty vindicating for her. But now her ex-boyfriend is running around town with Cameron Diaz, so that kind of sucks. And why do I spend so much time thinking about what Jessica Simpson must feel about everything? What is wrong with me?

To quote my roommate on this one: “Ew.”

John Mayer was seen on a date with Cameron Diaz in NYC on Tuesday night. “They went out to several places…It was the two of them, getting to know each other, out on the town,” says a source.

Diaz is in New York filming the romantic comedy What Happens in Vegas, and John Mayer is in New York being lecherous.

According to friends, the two already knew each other: “This was technically not their first time hanging out…they’ve hung out together with friends before. But this was the first time together like this. It’s new and developing…but they really like each other and it went well,”

I wonder what Jessica Simpson has to say about all this … she’s been laying pretty low lately. Come out and whine, Jess!!!

This thing’s gone viral in a big way. And, for the first thirty seconds or so, it’s hard to understand why. But you keep watching, and the damn thing grows on you. You can’t pull yourself away. It’s YouTube crack.

The kid singing the John Mayer cover (God, John Mayer must be fucking loving this), is Tay Zonday, a 25-year-old from Minneapolis who many are heralding as YouTube’s first music star. Personally, I think this is a viral flash in the pan, and not indicative of a lasting music career, but who knows? Enjoy.

Update:

Ha! And here’s John Mayer, doing a version of Chocolate Rain to the tune of Nelly Furtado’s “Say It Right.” I hate that I always love him.
