The weddings of 33 couples during the Grammy Awards were legally presided over by Queen Latifah. The rapper-actress-talk show host had to be sworn in as a commissioner by the state of California to perform the ceremony.

"You can call me Queen Commish for a little longer," she joked backstage Sunday night.

Latifah said she's not an ordained minister and her special powers expired at midnight.

"It was something I took very seriously," she said. "That is someone's life commitment to one another, you want to make sure you do it right. That's what sunk in for me."

The marriages took place in the aisle of the Staples Center during Macklemore & Ryan Lewis' performance of the gay rights anthem "Same Love."

"To have your wedding in front of 100 million people is pretty momentous," Latifah said. "I can say I was here and that will not leave me. I look forward to dashing off and signing all their wedding certificates."
