The 30-year-old Wolf of Wall Street actor created a commotion on the red carpet when he walked behind Cooper's interview with ABC's Robin Roberts. Hill waved to fans causing them to scream, and caught the attention of Cooper. After waving to each other from afar, Hill joined the American Hustle actor over at his interview.
"This is my date tonight," Hill joked, giving Cooper a hug. "I always assume Leo [Leonardo DiCaprio] is standing right behind me every time I do that . . . or Bradley," he quipped, of hearing fans scream.
Hill then acknowledged to Cooper and Roberts: "I just totally hijacked your guys' stuff." Completely giving up on the interview, Hill's mother Sharon then joined the boys while Roberts cut to commercial.
