Does anyone know if Nip/tuck will be back for a sixth season?

Yes, I think season 6 starts in January 2010 and part 2 of season 6 will be in January 2011. Kind of like how 2005 had 2 parts in 2008 and 2009.

Believe it or not, Nip Tuck has been canceled. I think this is the last season. Which is ridiculous because it happens to be one of the best shows FX has ever had. Apart from The Riches.

Unfortunately it is true, Nip/Tuck has been cancelled :-( This is the last season! That being said, I've personally started a petition to send to FX Networks and the writers of the show to bring it back. If you want to help bring Nip/Tuck back sign the petition and get your friends to sign it too! Here's the link:
