'House of the Dragon' star Olivia Cooke describes being hungover on her first day

If you're going to do a podcast with British comedian Alan Carr on a work night, apparently don't bring a bottle of wine.This was a lesson House of the Dragon star Olivia Cooke learned the hard way, after she got so drunk enough to chip her tooth the night before her first day on set."No one knew on set," Cooke explains in the Jimmy Kimmel Live! clip above. "Until now."Elsewhere she stayed pretty tight-lipped about what's coming up in the Game of Thrones prequel, except to say that the upcoming 10-year time jump has left her character Alicent's relationship with Rhaenyra even more frayed than it already was.
