They were supposed to renew their wedding vows, something they do each year on their anniversary. This year Mariah Carey and Nick Cannon celebrated their wedding anniversary in an undisclosed hospital in Los Angeles where Mariah gave birth to twins, a boy and a girl.

Mariah delivered Saturday about 10:07 a.m. Colorado time. The girl was born first, weighing in at 5 lbs. 3 oz. and was 18 inches long. The boy came soon after, weighing in at 5 lbs. 6 oz. and 19 inches. Mom, Dad, and the kids are all doing fine.

No names have been made public as of yet however Nick was quoted by People Magazine back in January, "They won't be crazy names like Carburetor or something, But they're definitely unique."
