Fans of Shameless are being given the opportunity to appear in the hit drama series.

Channel 4 is giving one lucky viewer the chance to win a walk-on part in the brand new series, sharing the screen with the Gallagher clan and the rest of the Shameless cast.

To enter, all viewers have to do is visit the Shameless MySpace profile (http://www.myspace.com/shamelessc4) and explain why they deserve to be part of the show.

Extra credit will be given to those who add MySpace profile pictures of themselves dressed as one of the characters from the programme.

The competition closes on Monday September 24 and the winner will be chosen by a Channel 4 judging panel.

For full terms and conditions, viewers should visit the official site at http://www.channel4.com/shameless.

Series five of the award-winning show will return to Channel 4 in early January 2008.
