A couple of weeks ago, I went on a little rant about an episode of Kathy Griffin’s show where Paris Hilton said she never performs a certain sexual act that we’ve all seen her perform multiple times on video.

What I didn’t mention was that during that same episode, Kathy & Paris’s trip was interrupted by Jill Zarin from Real Housewives of New Jersey York. The show made it seem as though Jill had just burst in on them and then wanted to tag along all day. Not so, claimed Jill, when I caught up with her at the 3 Olives party last night and grilled her about it.

“What happened is I was out there visiting colleges, and I was shopping on Robinson and I ran into their film crew and they were like, ‘Oh, Paris and Kathy are going to be here shopping, do you want to be in it?’ And I was like, ‘Sure, why not!’ And I walked into the store and we just gossiped and then I went to see American Idol. That’s why I was all dressed up – I was on my way to American Idol. So Kathy made that up when she said I wanted to keep shopping with them. I was going to see the Idol taping.”

I asked her what she thought about seeing Idol in person: “I was a little disappointed. It wasn’t what I was expected. I wasn’t a big fan of any one performer in particular — they’re all talented — but being inside the studio it wasn’t that impressive. It looks different on TV.”

I guess everything looks different on TV. Jill was kind and personable and not at all annoying when I chatted with her. Oh, and the reason she was looking at colleges? For her teenage daughter, who tagged along with her to the party and who I later spotted partying in the VIP area.

Meanwhile, Jessie from NYC Prep showed up and tried to walk the red carpet but got turned away … because she’s not 21 yet. Maybe if she had a famous mom?
