AceShowbiz - Nick Cannon's wife, Mariah Carey gave birth to a boy and a girl at a medical facility in Los Angeles on Saturday, exactly three years after she married Cannon in the Bahamas.

The couple had planned to renew their vows that day, but it was put on hold when Carey went into labour.

Cannon has now confirmed they went through with the ceremony on Sunday while Carey was still in the hospital, by asking their friend, Reverend Al Sharpton, to come to the medical facility to oversee the service.

The rapper/actor writes in a post on Twitter, "Thank you to The Rev Al who came all the way to the hospital to renew me and my wife's vows and pray with our children... Yep we just had a wedding in the hospital!"

Sharpton has revealed he also gave the couple's newborn children a blessing, adding, "I am just leaving Mariah Carey and Nick Cannon. She had twins yesterday on their 3rd anniversary. I had prayer with them and the babies... I also conducted the renewal of their vows and the blessing of the newborn twins. Mariah looks great, and the babies are beautiful... 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."
