Matt Damon is doughy, not fat

Matt Damon is worried he may lose his Sexiest Man Alive title.

The Bourne Ultimatum star – who was given the honour last year by People magazine – joked the 20 to 30lbs he gained for Steven Soderbergh’s upcoming thriller The Informant may disqualify him from the position.

He said: “I think I lost my title.”

The former heartthrob – who won an Oscar for co-writing Good Will Hunting with close friend Ben Affleck – also revealed he really enjoyed piling on the pounds for the role.

He added to People magazine: “It wasn’t necessarily that I needed to be fat. It was that I needed to be doughy.

“I just stopped working out and basically just ate whatever I wanted. I ate a lot of In-N-Out, a lot of burgers, drank a lot of beer and basically had a great time.

“When you’re in your 20s you can do that kind of stuff. When you’re in your 30s, it’s a whole different ball game.”

Meanwhile, Gone Baby Gone director Affleck has been quick to poke fun at his porky pal.

He said: “Some things are just self-evident and don’t even require making fun of. I mean, the man buys two seats on an airplane!”
