April 30 is double the pleasure for Mariah Carey and Nick Cannon. Not only did they welcome twins, but the couple celebrated their fourth wedding anniversary, too! Carey, 41, delivered the babies Saturday at 12:07 p.m. EDT at an undisclosed hospital in Los Angeles. Carey’s representative, Cindi Berger, confirmed the births to The Associated Press, saying the baby girl was born first, weighing 5 lbs., 3 oz., and was 18 inches long; her brother was next, at 5 lbs. 6 oz., and was 19 inches.
