UPDATE: MARIAH CAREY GIVES BIRTH TO TWINS, NICK CANNON RELEASES STATEMENT!!!

Mariah Carey finally gave birth to her twins!

The singer, 42, and her husband Nick Cannon welcomed their twin son and daughter on Saturday -- their fourth wedding anniversary! -- at an L.A. hospital at 12:07 p.m., her rep confirms.

According to Berger, the baby girl was born first, weighing 5 pounds, 3 ounces, measuring 18 inches long; her brother followed, weighing 5 pounds 6 ounces, and was 19 inches.

Carey and Cannon, 30, have not yet named their kids. Cannon rushed his wife to the hospital in their Rolls-Royce Phantom; the Grammy-winning singer was calm, assuming it was another false labor incident. When they arrived, Berger told the Associated Press, the first-time Dad was so nervous that he went to the wrong unit in the hospital, and had to be guided to the maternity ward by a nurse.

"It was right out of an I Love Lucy skit," Berger said.  The couple had musical accompaniment as Carey delivered their kids: "We Belong Together," Carey's smash #1 single from 2006.
