1D's Liam apologises for 'stupid' building ledge photo

One Direction singer Liam Payne has apologised after his friends tweeted photograph of him standing on the ledge of a high-rise building.

The boyband star described what he did as "extremely dangerous", adding that it was "stupid" and "irresponsible".

In the now-deleted photograph, Payne, 20, is standing on a ledge of a tower block with a city thought to be London seen sprawling behind him.
