Mariah Carey and Nick Cannon

Mariah Carey and husband Nick Cannon welcomed their twins into the world Saturday at 9:07 a.m. at an undisclosed Los Angeles hospital, according to the Associated Press. As expected, one was a boy (weighing 5 lbs., 6 oz. and measuring 19 inches) and the other was a girl (weighing 5 lbs., 3 oz., and measuring 18 inches). Carey's rep, Cindi Berger, says that Carey and Cannon have yet to name the twins.

The twins' birthday coincides with the couple's third wedding anniversary. Berger says that after driving Carey (who thought her labor pains were another in a string of false alarms) to the hospital in a Rolls-Royce Phantom, Cannon got lost in the hospital and had to be guided to the maternity ward by a nurse.

After the twins were born, they fittingly listened to Carey's 2005 smash "We Belong Together," Berger says. The twins are the couple's first children, and possibly their last: Carey reportedly has said that after these, she's "done."
