NEW YORK (AP) — A day after becoming parents to twins, Mariah Carey and Nick Cannon renewed their vows with a hospital ceremony conducted by the Rev. Al Sharpton.

Saturday was the couple’s third anniversary — and also the day when Carey gave birth to a girl and a boy in Los Angeles. On Sunday, Sharpton blessed the babies, and also presided over a ceremony where the couple renewed their vows.

Cannon tweeted words of thanks to the civil rights activist and said: “Yep we just had a wedding in the hospital!”

Sharpton tweeted that Carey looked “great” and that the babies are beautiful.

No names for the newborns have been announced.
