if anyone knows why could you please tell me because i'm really curious!!

Same here

I read that too (shouldn't this be in celeb gossip?)

I've read that...

Paris had a little party in her flat,
she wanted to show her friends a tape and Nicole put the "One night in Paris" tape !
That's it !

Omg!

I was also wondering, as no one has said why here in America. Wow.
