Guests at Universal Studios [2] got to enjoy a rather unexpected concert on Friday, thanks to John Legend [3]. During a trip to the amusement park, the 40-year-old singer [4] apparently got a little tipsy and took the stage to croon an impromptu (and off-key) version of his 2013 single "All of Me." Oh, and did we mention he was dressed in a onesie with his face printed on it? "We went to @unistudios last night to do Horror Nights [5] before they shut it down," he captioned a clip of the mini show. "Costume theme was onesies. . . . Someone made Chrissy a onesie with my face on it and of course I had to wear it. Then I found a reluctant DJ with a mic and serenaded myself. It was a night."

Chrissy posted about the hilarious moment [6] on Twitter, writing, "John got wine drunk and sang a song at universal studios last night." She then provided a little background on how the onesie-clad singer ended up on stage [7] in the first place: "The whole joke was supposed to be that literally no one was watching or at the stage but then he got on stage and was like ITS ME JOHN LEGEND [8]." He might not sound like his usual self [9], but you have to love the passion.
