What happens in Vegas, stays in Vegas – but when Sin City takes over South Beach, all bets are off. On Monday night, owners of the Bellagio's ultra-hip nightclub Light rented out Mynt on Miami's Collins Street for a bash that featured an impromptu 2 a.m. dance-off between Jennifer Lopez and 'NSync's JC Chasez. "J.Lo was dancing all around like she was single ... even though she was there with Marc Anthony," says a spy, who watched the two stars take turns popping and locking on tabletops and speaker boxes to songs including "Seven Nation Army" by the White Stripes. "I would say JC won because he was up there for almost an hour and a half straight," another onlooker tells the Daily Insider.

In his new movie, Eternal Sunshine of the Spotless Mind (opening March 19), Jim Carrey and costar Kate Winslet try to rescue their failing relationship by having their bad memories erased. But in real life, the actor says he's found some less extreme ways to cope with disappointment. "I've had a lot of conversations with myself, a lot of summations," Carrey tells us. "I think the real magic about this movie is that you accept the flaws, and you accept what was wrong, and you move on and you love the person for who they are, flaws and all."
