Hugh Grant is "dreading" turning 50.

The British actor - who hits the half a century mark on September 9 - is so unhappy about reaching the milestone age he has even joked about ending his life at a euthanasia Clinic.

He said: "I'm dreading it. There is this place in Switzerland called Dignitas. I'm going to go to Dignitas on my 50th birthday - 50 is enough!"

The 'Four Weddings And A Funeral' star - who has never married - also admitted he lost his sense of humour when started exercising more in a bid to escape crippling panic attacks which often struck him while he worked.

He explained to Britain's OK! magazine: "I get these panic attacks. So I have always tried to do everything I possibly can - herbal remedies, chemical remedies. Running was the only thing that really helped.

"It calmed me down, so I didn't have the panic attacks. But at the same time, I found it lowered my sense of humour. I lost my edge a bit. So in the end, I stopped running.

"It's not audiences, I love an audience. Put me on stage in front of a thousand people and I'm very comfortable. It's cameras. I don't like them."
