Last night, Mariah Carey and Nick Cannon threw a big party in Vegas to celebrate one year of marriage. After a lavish dinner, Nick brought Mariah to tears with a surprise video tribute of their best moments and a shower of balloons. When the two eloped last April, we doubted that it would last. That said, the two seem as blissful together as ever, and the only rumors that surround them are about whether or not they'll have kids. I admit that I might have misjudged the couple, but tell us — are you surprised that Nick and Mariah have lasted this long?
