Zach Galifianakis says leave my beard alone!

Robert Downey Jr. and Zach Galifianakis walked the red carpet for the UK premiere of their latest comedy, Due Date.

The film follows the story of a highly strung father-to-be Peter Highman (Downey), who is forced to hitch a ride with aspiring actor Ethan Tremblay (Galifianakis), in order to make it to his child's birth on time.

Galifianakis, who also starred in the hit film The Hangover, has been receiving quite a bit of attention about this beard.

But the actor wishes people would leave it alone, and said: "If Adrien Brody was here you wouldn't go what's with you're big nose Adrien! Why don't you get rid of that big nose Adrien! So that's the way I feel when people ask me about my beard!"

Last years X Factor hopeful, Lloyd Daniels, also attended the premiere. The 17 year-old singer announced that he has a single coming out next February, and a calendar at the end of this year.

Due Date his UK cinemas from November 5.
