Bradley Cooper Went Commando to the White House

American Hustle star Bradley Cooper revealed that when meeting President Barack Obama and French officials last week, his outfit was missing one piece de résistance: underwear.
Cooper, 39, has gained about 15 lbs. in four weeks for an upcoming role, he said Monday on The Ellen DeGeneres Show. He decided to dust off his Golden Globes tux for Tuesday's White House State Dinner, not realizing the suave suit no longer fit.
"I'm getting dressed like 10 minutes before I was supposed to go, and literally the pants go up to like here," Cooper recalled, pointing to his thighs. "I just started laughing, actually. This is hilarious. I'm going to meet the president. So I had to go commando, number one, because there was no room at all."
Girlfriend Suki Waterhouse didn't seem to mind. The 22-year-old model stuck by her man's side throughout the night as he chatted with dignitaries and fellow actors like Veep's Julia Louise-Dreyfus.
Just how close was Cooper to a wardrobe malfunction?
"They were crazy-town tight," he told DeGeneres of his pants.
