Congrats to Mariah Carey and Nick Cannon on the Saturday arrival of their twins. The girl was born first, weighing in at 5 lbs, 3 oz; 18 inches long. Next came the boy: 5 lbs, 6 oz; 19 in. No names released yet. Cute, cute! Even cuter: yesterday was also Nick and Mariah's wedding anniversary. All together now: awwwww!
