Beyoncé & Jay-Z and Mariah & Nick Ring in 2009 in St. Barts!!

Time to "Pop Champagne". Power couples Beyoncé and Jay-Z and Mariah Carey and Nick Cannon celebrated New Year’s Eve together at Nikki Beach club in St. Barts. L.A. Reid and his wife Erica also joined the festivities at the Caribbean destination. Mariah can be seen sitting on Nick’s lap at one point, while B takes pictures of her friends. The couples look like they had a lot of fun—laughing, dancing, and sipping drinks throughout the evening. Looks like so much fun!!
