The parties were kicking last night in Vegas! From 50 to Xtina there were plenty of hosted events to choose from. As expected, Paris hit them all - how does she do it? In fact, at the Christina hosted LAX party, she got the mic and told Xtina, "Congratulations to the most beautiful pregnant woman in the world. You're gorgeous!" Apparently Christina was shocked at being exposed but then laughed it off with her husband Jordan. Hopefully this is just a peek at what will happen tonight on the big show! Obviously everyone is buzzing about Britney's big opening act. She's been busy rehearsing but she also made sure to party the nights away. Hopefully she is sleeping in and eating well so she can have energy to wow us all tonight! Check back later where we will be live chatting and voting on everyones' red carpet looks and performances!

Lots more images of 50, Paris, Britney, Diddy, Cassie, Mario Lopez, and many more so read more
