Bradley Cooper is learning how to flip burgers. The 36-year-old Guardians of the Galaxy
star had a lesson at Burger King in Leicester Square, London on Sunday night to help him master ''the art of the flip'' in preparation for his role as a chef in the upcoming film Adam Jones
. A source told The Sun
: ''Bradley was training alongside genuine Burger King staff. The aim was to learn the art of the flip, which he nailed fairly quickly. There was no real fanfare from him. You'd never know he was a big star by the way he spoke to people. He spent Sunday night learning the skills while the restaurant was open to the public and then filmed for most of the day on Monday.'' However,
it's not just fast food chains that have been helping the hunky star - who is dating model Suki Waterhouse, 22 - perfect his culinary skills as he's also been taking advice from celebrity chef Gordon Ramsay. The F Word
star, 47, said previously: ''As well as giving Bradley a few top tips on cooking, I've taught him the most important thing he needs to know in order to get by in a kitchen - how to swear.''
