Last night on Jimmy Kimmel Live, Kate Mara confirmed the implacable “professionalism” of Kevin Spacey during their House of Cards shoot. Just to get the stoic actor to crack a smile, she had worn pasties of Kevin Spacey’s head in a love scene — “But nothing!” And the Barack Obama pasties on her second attempt didn’t cut it either. Plus: Conan completely embarrassed Jennifer Lawrence with an old clip of her role on Monk. Remember that? Probably not, because she played the over-enthusiastic tiger mascot. Also, Justin Bieber displayed some awkward moments during a round of fake basketball, even bringing Jimmy Fallon’s dancing to a halt as he made out with a mannequin’s head — with tongue, too. Plus, Eric Stonestreet is proud of his Elvis impersonation. Watch our compilation to see what you missed.
