There are even reports they went to Mexico and got married. Do you think that's true?
I'm positive that's not true. He took her down to Mexico to get pictures he could sell. But he is still spending lots of time with her, which is kind of surprising to us because Britney's parents are supposed to be controlling and putting this tight rein on her. But for some reason they're still allowing him to visit.

For a while [Britney, Paris, and Lindsey] were totally competing for media attention with one another. They were all actively vying to see who could get more headlines and pictures in the press. We were glad to help them allSince he is at a rival agency, are you a little bitter about the access his relationship gives your competitors? Is it sour grapes since he was getting all these exclusives?
No, we felt like for a month he was controlling her. Normally her dating someone would be huge news, but to be honest, the fact that it was one of our competitors made it not so appealing for us.

Are there ever pictures you wouldn't sell or put up on your blog?
We self-censor sometimes. It's your editorial discretion that decides what you're going to put up and what you're not going to put out. And it changes from moment to moment. We've certainly gone too far sometimes. We've made mistakes. But everyone in the media makes mistakes sometimes. The other day we had Jennifer Garner bending over and her butt-crack was hanging out of her jeans, and I was like no way we are using that. She was there with her kids and I don't want to see her butt-crack; it's not necessary. Whereas with other stars that would be the focus of the entire story. I can be plenty tasteless, but everyone has their limits, and I'm a mom and I feel like that happens to the best of us. Jennifer's not Britney or Paris Hilton.

What makes you treat Paris Hilton, Britney Spears, and Lindsay Lohan differently than, say, an actress like Julia Roberts or Cate Blanchett?

First of all, I think Paris Hilton was at a different level, but now I think Britney and Lindsay Lohan are there, too. They've all aggressively courted the media's attention, and especially the attention of the paparazzi. Whereas you have other celebrities who have specifically not asked for attention at all, and even shun it. Julia Roberts doesn't seem to want to be in the media at all. And she's a mom and she has kid and a family.

But Britney, Paris, and Lindsay are open game?
Yes. Because they compete for our attention and they don't care how they get it. When you see certain things slip out [laughs], whether it's the nipple slip or oops-no-underwear slips, I really don't get the feeling that any of that is unintentional or accidental. For a while it was obvious that those three girls were totally competing for media attention with one another. For a few months they were all actively vying to see who could get more headlines and pictures in the press. We were glad to help them all.
