American Hustle star struggled to fit in tuxedo

Bradley Cooper has revealed that he went commando to a state dinner at the White House earlier this month.

The actor was forced to ditch his underwear to meet Barack Obama when he discovered that his trousers were too tight following his recent weight gain for a film role.

I’ve gained about 15lb in four weeks and nothing fits me anymore,’ says Bradley, 39.

So I wore the tuxedo I wore to the Golden Globes. I just sort of threw it in the bag and brought it and went to Washington, DC.

Then I’m getting dressed like 10 minutes before I was supposed to go, and literally the pants go up to like here.

I just started laughing, actually, [like], “this is hilarious, I’m going to meet the President.”

So I had to go commando number one ’cause there was no room at all. I did. I had to.’

Bradley – who attended the prestigious do with model girlfriend Suki Waterhouse – tried his best to stay seated so that no-one would notice his snug slacks.

They were crazy-town tight,’ the American Hustle star tells the Ellen DeGeneres Show.

I couldn’t stand up really. So it was really great. And you have to walk up the stairs, and it was a nightmare. But I made it through.’
