John Legend Takes MC Hammer's "U Can't Touch This" to a Whole New Level

After John Legend and Common's emotional "Glory" performance at the Oscars, the two reunited on stage in a friendly lip-sync battle Thursday night. John and Common both brought their A-game dance moves as they battled it out in a two-part competition. Common chose The Jackson Five's "I Want You Back" as his first song, and then John, wearing grills, busted out a rap to Juvenile's "Slow Motion." At one point, John was having so much fun that he said, "I forgot I was in a competition, man. I was helping [Common] too much [by dancing along]." Watch the first part of the battle above, then check out their epic renditions of Lionel Richie's "All Night Long" and MC Hammer's "U Can't Touch This" below.
