Hugh Jackman, an actor as comfortable on Broadway belting show tunes as he is slicing up ninjas as the mutant Wolverine in the "X-Men" film franchise, has finally come to grips with those two worlds in a hilarious musical parody

The 45-year-old, a guest on BBC Radio 1's "The Matt Edmondson Show," was presented with some Wolverine-themed lyrics set to the Les Mis number "Who Am I?" The former Oscar-nominated Jean Valjean gives it his best shot - with a great deal of the song dedicated to his hellish restrictive diet and bulking routine

“What I do is I eat everything in an eight-hour period … It’s called the 16-8 diet," he said last year. "For 16 hours of the day I fast, so I don’t eat. So between 10 in the morning and 6 at night — this is why I’m burping because I ate a steak literally before I came out — I eat 5,000 calories and then I eat nothing,” Jackman said. “I literally talk to myself like I’m training: ‘One more mouthful, come on man, you can do it. Just one more mouthful. Half a chicken breast to go and you’ve got it! Only two meals left.’”
