On Friday's Ellen, Chrissy Teigen jumped out of the talk show set's infamously surprising coffee table to spook husband John Legend while he was guest-hosting for DeGeneres. Teigen's unexpected cameo came after Legend showed a joke version of his 2013 "All of Me" video with Ellen playing his love interest. (Teigen, of course, played his real-life love interest in the actual visual.) "Don't tell Chrissy, guys," Legend quipped. "She'll be very, very jealous of Ellen." That's when Teigen popped out of the table, screaming, "What are you f**king doing?!" She then added, "That was the hardest thing I've ever done. I didn't mean to swear, I'm so sorry." Legend then remarked that he had no idea Teigen was hiding inside the table and said, "If you wanted to cheat on me, you could probably get away with it." Teigen shot back, "Oh no, I have a million times." Not to be outdone, Legend said, "But I'm the Sexiest Man Alive, how could you possibly?"
