Jack Black says cheeseburgers are his "heroin".
The 'School of Rock' star admits he can't get enough of the tasty food and joked he should be attending Overeaters Anonymous.
He said: "I'm not an alcoholic. My vulnerability really is cheeseburgers. That's my heroin. That's seriously what I have to struggle with. That's more of a threat to my life than anything else. That's my addiction. If anything, I should go to Overeaters Anonymous."
The 46-year-old actor also insists he has no plans to slim down as he thinks it could "actually ruin [his] career".
He added to The Times magazine: "I could, but who has time for all that crap? Was I supposed to do that at four this morning before I took the kids to school? I don't know how Gwyneth Paltrow does it. I have to have a sit-down, a heart-to-heart with Gwynnie. You know what? Hope springs eternal, but I don't know that I want to Chris Pratt it out now. I think that could actually ruin my career. People will be like, 'What happened to Jack? He used to be funny when he was fat.'"
