It's been a busy week for Mariah Carey and Nick Cannon!

One day after the singer, 42, gave birth to twins, the couple renewed their wedding vows with a hospital ceremony conducted by Rev. Al Sharpton on Sunday.

"We just had a wedding in the hospital!" Cannon, 30, confirmed via Twitter.

"Mariah looks great, and the babies are beautiful," Sharpton, 56, added. "I am so moved by the sincere spiritual commitment of Mariah and Nick. They have not let success separate them from God. I am so proud."

According to Carey's rep, 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 have not yet named their children.
