Justin Timberlake has admitted that he feels "uncomfortable" when he has to watch himself on the big screen.
Timberlake told The Late Show with David Letterman about feeling awkward while having to sit through a screening of 'In Time'.
He said: "It is wildly uncomfortable. For this screening, I wouldn't have stayed but I had basically 40 friends who came to the movie.
"I felt like it was the first time they genuinely wanted to see me in a movie, and not Mila Kunis and Cameron Diaz... I sweated a lot... Not good stuff."
Timberlake, who originally found fame with boyband *Nsync and has since had a successful solo music career and is now trying his hand at acting, added: "You're definitely critical of your performance, always. But I find the same with music, too.
"If a song of mine comes on the radio, which sometimes it still does, I find that I naturally want to change the channel. You pick it apart."
'In Time' is released on November 1.
