Lady Gaga leaves BBC Broadcasting House in London after taking part in The Radio 1 Breakfast Show with Nick Grimshaw.

The superstar co-hosted Nick Grimshaw's Radio One breakfast show in teeny-tiny cut-off denim shorts and a silver vest that flashed some serious flesh.

She teamed the look with Doc Marten boots and sunglasses.

As she left the BBC's Broadcasting House, she was greeted by a gaggle of her fans - affectionately dubbed Little Monsters - and took time to take selfies and sign autographs.
