Mariah Carey, Nick Cannon Welcome Newborn Twins

May 1, 2011— -- Mariah Carey and husband Nick Cannon welcomed a baby girl and boy on Saturday, their third wedding anniversary.

"My wife just gave me the most incredible anniversary gift ever in life," Cannon tweeted on Saturday. "I won't ever be able to top this!"

Carey's representative Cindi Berger confirmed to The Associated Press that the 41-year-old singer gave birth at 12:07 p.m. ET at an undisclosed Los Angeles hospital. The baby girl was born first, weighing 5 pounds 3 ounces, and was 18 inches long; the baby boy was 5 pounds 6 ounces, and was 19 inches.

Berger also told the AP that Cannon, 30, drove Carey to the hospital in their Rolls-Royce Phantom, and was so nervous that he went to the wrong department in the hospital, needing to be led to the maternity ward by hospital staff. The new mom and dad listened to Carey's 2005 hit "We Belong Together" after the children were born.

In October 2010, Carey confirmed her pregnancy in an "Access Hollywood" interview, revealing that part of the reason she and Cannon initially kept her pregnancy a secret is because she had a miscarriage two years ago.

"It kind of shook us both and took us into a place that was really dark and difficult," Carey said. "When that happened ... I wasn't able to even talk to anybody about it. That was not easy."

Carey and Cannon met during a video shoot for her single "Bye, Bye" and were married in 2008 at Windermere Island in the Bahamas.

Did the couple plan for the birth to coincide with their anniversary? No, Cindi Berger told People.

"No, not even Mariah could plan that."
