The Hangover star showed he certainly knows how to wear a suit as he exited the Tom Ford Autumn/Winter collection showing on Monday night (17 February).
We wonder if he was going commando?!
Bradley, 39, recently told The Ellen DeGeneres Show that he ended up sans underwear for a glitzy bash at the White House that he attended with Suki earlier this month.
But before you go thinking the naughty boy had planned it, turns out he hadn't anticipated his Golden Globes tuxedo wouldn't fit him while he's been gaining weight for a new movie.
Bradley explained he's gained 15lbs in four weeks for his new role – and has 20lbs more to go – which meant his trusty tux left absolutely zero room for underwear underneath. Ooh la la.
But, back to event's in London last night, and Bradley kept a tight grip on model girlfriend Suki, who walked behind him, as they made their way through the throng of photographers to reach the car.
The stylish couple had been seen chatting with designer Tom Ford after the show, which was attended by celebrities including James Corden and Vogue boss Anna Wintour.
Bradley's been over in the UK for a few days, firstly to attend the BAFTAs at the weekend, where he was nominated in the 'Best Supporting Actor' category for his role in American Hustle, and also to support Suki as she walks the catwalks at LFW.
But it seems Suki might not be supporting him up close at next month's Academy Awards (where he is also nominated), as Bradley told Ellen who he takes as his date will come down to another two important women in his life: his mum and his sister.
