Love is in the air today for Mariah Carey and Nick Cannon, who celebrated their one-year wedding anniversary in Vegas at the Palms Casino Resort, according to “Just want to say happy anniversary to the woman I love. She is the most amazing person in the world. To all the people who thought this wouldn’t work out, this is going to last forever. She is my soul mate. Here’s to many, many years together,” says Cannon, who hit the turntables at the star-studded bash.—QS
