Colin Will Have to Beef Up

Hollywood heart-throb Colin Farrell is pigging out on junk food to bulk-up for his latest film role.

The Irish playboy is set to woo thousands of female fans by gaining an extra 20lbs to play Alexander the Great.

But the hell-raising hunk claims he never works out and will struggle to get in perfect shape to play the legendary warrior.

The 26-year-old star said: "I don't work out - no way.

"I've done a couple of times for various gigs but not much.

"Nothing like what I'll need to do for Alexander.

"I'll have to put on about 20lb of muscle.

"There'll be so much swordplay - I mean, he was a hunter when he was two years old, killing wild boars.

"So there's a bit of catching up to do."

Method actor Robert De Niro famously piled on 60lbs pounds to play boxing legend Jake La Motta in Raging Bull.

And Men In Black star Will Smith spent months in the gym beefing up for his Mohammed Ali boxing biopic.
