In a scene that would have Hermione in quite a tizzy, Harry Potter star Daniel Radcliffe got hot and heavy with a male fan at an awards show in London.

The 18-year-old Harry Potter star went on stage to collect two top theatre awards for his West End debut in Equus - including one for his naked torso.

But while onstage host James Corden, 29-year-old actor and writer of BBC2 show Gavin and Stacey, grabbed the star, clasped his hands on his face and held on tightly for an embarassingly lingering kiss.

Daniel triumphed at the Whatsonstage.com Theatregoers' Choice Awards.
