Hugh Jackman thinks DWAYNE 'THE ROCK' JOHNSON's diet is ''crazy''.

The 44-year-old actor relied on his Hollywood pal to help him bulk up to reprise his titular role in new superhero movie 'The Wolverine' - after losing a considerable amount of weight filming musical movie 'Les Miserables' - and the 'Fast & Furious 6' star advised him to follow his own gruelling fitness regime.

Hugh told BANG Showbiz: ''I called my buddy The Rock for tips. I lost weight doing 'Les Mis'. He said, 'Here's the deal - three hours in the gym and 6,000 calories, eating very lean. You gotta do that for six months.' I did it and let me tell you, The Rock is crazy! He is insane. But we did it and the results are there.''

Hugh's superhero diet mainly consisted of protein-packed chicken breasts, but the star admits he can no longer stand the sight of them after filming the movie.

He added: ''Let me just say, I will not be eating chicken breasts for lunch anymore!''

Dwayne, 41, recently revealed his strict diet and exercise plan as he films new action movie, 'Hercules: The Thracian Wars', which includes no less than seven meals a day over a course of 22 weeks mainly consisting of chicken, halibut fish, broccoli, asparagus, baked potatoes and egg whites.
