Daniel Radcliffe is to be honoured by LGBT helpline the Trevor Project for his support.

The Harry Potter actor, 21, will receive the helpline’s ‘hero’ award for raising awareness of its work.

He has filmed public service announcements for the Trevor Project and given the charity sizable donations.

Radcliffe told AP: “It’s fantastic. The fact that they think of what I’ve done by promoting awareness of the Trevor Project itself and the issues that it works to promote and help is a great honour.

“The people that are doing the heroic things are the people answering phones 24 hours a day in the Trevor call centres. I think that out of everything that I’ve done so far in my career, I think this is absolutely one of the most important, if not the most important, thing that I’m associated with.”

The star will receive the award at a ceremony in June. Past recipients include screenwriter Dustin Lance Black and former Miss America and Ugly Betty actress Vanessa Williams.

Radcliffe, who is straight, has brushed off rumours about his sexuality, saying he doesn’t mind what people think.
