Nick Cannon turned 28 today and Mariah got the fun started last night with a birthday party for him at Pure in Las Vegas. She slipped into a typically tiny black dress and put to rest any pregnancy rumors with her glass of wine as Nick played DJ and gave her plenty of shout outs. Their trip hasn't been all play though — the couple came to Vegas on Saturday to film Mariah's new music video for "I Stay in Love," which Nick directed. With Mariah now her own manager and putting her husband to work, it looks like these two are taking on more projects together other than just kissing for the cameras.
