A teary-eyed Mariah Carey and her husband Nick Cannon celebrated their first wedding anniversary at Moon nightclub inside the Palms Casino Resort in Las Vegas on Thursday.

Guests including L.A. Reid, Tyrese, and Floyd Mayweather watched a video Nick produced of the couple’s “Love Story,” which made his wife cry.

“This is the most amazing person in the world,” he told guests about his wife. “I dedicate my life to her daily, and together this union is gonna last forever. She is my rock.”
