Mariah Carey & Nick Cannon Welcome Twins

April 30 is double the pleasure for Mariah Carey and Nick Cannon. Not only did they welcome twins, but the couple celebrated their third wedding anniversary, too!

The singer, 42, delivered the babies Saturday at 9:07 a.m. 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 is 18 inches long; her brother was next at 5 lbs., 6 oz. and is 19 inches long.

And it was just as Cannon, 30, predicted.

“I’m not trying to be a psychic, but we renew our vows every year so … It’s probably going to be in the hospital this year. I can feel it,” Cannon said Thursday when he guest-hosted The Talk. “We got the minister coming in, so this gown will not be a wedding gown, but a hospital gown.”

Berger tells PEOPLE “she’s doing great” and they were listening to Carey’s “We Belong Together” after the children were born. “I spoke to both of them and they are both completely overjoyed.”

Asked if the birth was planned to coincide with her anniversary, she said: “No, not even Mariah could plan that.”

“Nick was very nervous and Mariah was completely calm. Mariah thought it was another soft labor and Nick was driving her to the hospital. She was very calm and the music was blasting,” she added. “When they walked into the hospital, [Nick] was going the wrong way and they nurse redirected them to go the maternity ward, and I said to her, ‘That’s right out of I Love Lucy,’ and she laughed.”
