Chris Pratt Takes the Stage to Sing After the Jurassic World Premiere

After the LA premiere of Jurassic World on Tuesday, Chris Pratt capped off his big night by hitting the stage with Jimmy Buffett during the afterparty. Videos taken at the party show Chris belting out "Margaritaville" with the singer, giving shout-outs to his costar Bryce Dallas Howard and his mom, who celebrated her 60th birthday. His Parks and Recreation costar Retta was among the guests, and during the afterparty, she posted a picture of Chris on stage and joked, "Only @prattprattpratt would get on stage at his premiere party to rock out with #JimmyBuffet."

Earlier in the day, Chris stopped by Jimmy Kimmel Live, where he hilariously talked about his nipples and sweetly mentioned his mom's birthday, saying, "She doesn't know this, but Universal made her a great big cake. I've got my mom, my brother and sister, their significant others and all their children, friends of the family. I've got a huge group of friends and family coming to the show tonight."
