New Delhi, Apr 3 : Jim Carrey has become a huge fan of Bikram yoga, courtesy her girlfriend Jenny McCarthy''s toned bottom.

The actor is absolutely in love with the Bikram yoga - despite having never tried it himself - because he can''t get enough of the 36-year-old former Playboy model's toned derriere, reports the China Daily.

"Jim is absolutely in love with Bikram yoga and he''s never tried it, strictly on the fact he loves the way my butt looks, although he would love me, I think, at 250lbs," McCarthy said.

McCarthy, who has dated the comic actor for three years, has admitted that she works hard to keep in shape.

"I do 90 minutes a day. That''s Bikram yoga and also healthy food," McCarthy said.

However, living with Carrey is causing her healthy-eating regime to suffer because he is trying to out on weight for upcoming movie ''The Three Stooges'', where he will play overweight comedian Curly Howard.

She told Access Hollywood : "He said, ''You know, I''m going to have to gain 40 or 50 pounds for this role.'' And I said, ''Oh my god! I get to be dating Curly!'' That is the greatest thing ever.

"I hope I don''t have sympathy weight because he''s going to be eating donuts and I''m going to be going, ''Ooohhh!'' Especially during PMS," she added. (ANI)
