Mariah Carey, Nick Cannon Welcome Twins!

Mariah Carey and Nick Cannon welcomed their baby son and daughter today - on their third anniversary no less! April 30 was quite the day for the family!

The legendary singer delivered the babies just after noon today in Los Angeles.

Carey's rep, Cindi Berger, said the baby girl came first, weighing 5 lbs., 3 oz., and was 18 inches; her brother was next, at 5 lbs. 6 oz., and was 19 inches.

As for the twins' birthday, Nick seemingly called it.

"I'm not trying to be psychic, but we renew our vows every year so ... It's probably going to be in the hospital this year. I can feel it," he said Thursday.

"The minister's coming. This gown won't be a wedding gown, but a hospital gown."

Carey's rep tells People "she's doing great" and that the whole family were listening to Carey's "We Belong Together" after the children were born.

Those two kids are gonna have some awesome lullabies growingup. Just saying.

Asked if the birth was planned for April 30, Berger said: "No, not even Mariah could plan that. But I spoke to both of them and they are overjoyed."

Which of the two had the butterflies before the big moment?

"Nick was very nervous and Mariah was completely calm."

"Mariah thought it was another soft labor and Nick was driving her to the hospital and she 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."

"I said to her, 'that's right out of I Love Lucy,' and she laughed."

Long before the births, the couple made no secret of their desire to have children. Nor did they shy away from revealing pregnancy photos.

We're glad everyone is healthy and happy. Congratulations again!
