On the Marriage Front...

It's hard to believe that Nick Cannon and Mariah Carey have been together for a whole year, but they have. The cougar and her cub celebrated their first wedding anniversary Thursday night in Las Vegas at the Palms Casino Resort. According to Entertainment Tonight, they gathered with a large group of family and friends at Simon at Palms Place for dinner. The tables were decorated with candles and a sign that said, "Happy Anniversary Mariah & Nick." Afterwards, the party moved to the Moon Nightclub where guests enjoyed a five-tier cake and a thousand balloons were released into the sky through the moon roof.

While it wasn't disclosed exactly what Mariah gave Nick, they said that Nick presented her with a video compilation of moments from their first year of marriage. Aww...

On the flipside, Kelis and Nas are calling it quits after more than four years of marriage. According to E! Online, Kelis -- who is expecting their first child this summer -- is the one who filed for divorce. Her rep has requested privacy.

Kelis and Nas said, "I Do," on January 8th, 2005 in Atlanta after a two-year engagement. The new baby will be a boy, and Nas has a teenage daughter from a previous relationship.
