Dreamy Patrick Dempsey has been treading the red carpet at the UK premiere of his new film.

The 80s heart-throb - now best known as Dr Derek Shepherd, aka McDreamy, on US drama Grey's Anatomy - has been in London promoting Made of Honour.

Dempsey plays womaniser Tom, who doesn't realise he's in love with his best friend until she is about to marry someone else.

He said he enjoyed taking time out from his TV schedule to film the new romantic comedy.

"I had a really good time. It was a lot of work because we were constantly working on the script.

"Paul (Weiland) was a wonderful director because we did a lot of improvisation and really made it relaxed and easy, and hopefully that's the experience you get when you're watching it."

Made of Honour opens on May 2.
