Channing Tatum thought his People magazine's Sexiest Man Alive 2012 title was a joke.

The 32-year-old actor was recently awarded the honour but admitted he didn't believe it at first because he is such a prankster.

He said: ''I play a lot of practical jokes so my first thought was 'Y'all are messing with me', I told Jenna [Dewan Tatum - his wife] after we'd been in the bathtub washing our dogs because they'd gotten skunked. She was like 'What?' ''

Despite his sexy status, the 'Magic Mike' star still thinks he has an ''inner fat kid'' and can't resist watching TV weight loss shows.

However, he admits they often leave him in tears because he understands the drive of the contestants.

He told People magazine: ''I cry every time I watch 'The Biggest Loser'. I don't know why, I think it's the inner fat kid in me. You see these people just want it so badly. Certainly always when they're like hitting the boxing mitts and they all just break down crying.''
