Mariah Carey: Why Hubby Nick Cannon Made Her Cry

Happy Anniversary, Mariah and Nick!

Mimi and the hubby celebrated their first year of marital bliss last night in Las Vegas.

Read on to find out what they did, where they were doing it, and why Mariah cried!

Carey, wearing a floor-length white gown, and a tux-clad Cannon kicked things off with dinner for about 50 people at Simon at Palms Place. The comfort-food menu included surf and turf, macaroni and cheese and mashed potatoes, followed by crème brûlée and chocolate-chip cookies for dessert.

The party then headed over to Moon nightclub, where Cannon surprised his wife, who had changed into a pink Georges Chakra couture minidress, with a video montage highlighting moments from the past year. According to People mag, Carey was brought to tears.

If the dessert back at the restaurant wasn't enough, the couple then served up a five-tier Duncan Hines yellow cake.

Cannon was also put to work: He actually deejayed the party. Guess Mariah may not be his sugar mama after all.
