Justin Timberlake is the ultimate wedding guest.
Following the U.S. Supreme Court's landmark decision to legalize gay marriage across the nation on Friday, Jessica Biel's old college roommate Dana Panzer married Amy Wicker, and Justin Timberlake was there to make their day even more special.
"All the fellas gonna look at the ladies, who just got married tonight," Timberlake sang to the brides and their guests to the familiar tune of his hit, "Senorita." "And all the ladies gonna look at the ladies, you know what I'm saying?"
Ever the perfect entertainer, Timberlake even encouraged the brides to join in. "Amy, say 'It feels like something's heating up. Can I leave with you?'" he sang. "Dana, I don't know what I'm thinking about, really leaving with you," and they did just that.
But he didn't just perform that one song! Find out how he was able to "get Amy and Dana on the floor."
Love won on Friday, but for Dana and Amy, their wedding took the cake as they had one of the best wedding singers to top it all off!
