Jack Black set to diet

Jack Black is to go on a diet in the New Year, it has emerged.

The ‘Gulliver’s Travels’ actor has made a resolution to drop 50lbs and is planning a strict exercise and diet regime to achieve his goal.

Asked about his resolutions for 2011, Black told ‘Access Hollywood’: “I’m gonna drop fitty. I’m gonna drop fitty pounds.

“How many quarter-pounders with cheeses is that? I’m gonna drop 200 quarter-pounder with cheeses. (sic)”

He jokingly added: “Push-ups, sit-ups, and a strict diet of … raisins. That’s my plan.”

Black attended the ‘Gulliver’s Travels’ premiere in Los Angeles last Saturday but was not accompanied to the family movie screening by his sons Sammy, four, and two-year-old Thomas, because they do not know he is famous.

The actor – who is married to musician Tanya Haden – explained: “I didn’t bring my babies because they don’t know I’m famous yet. I’m trying to keep it well-hid. They’re like: ‘Whatever. Daddy’s daddy.’ They think I’m a salesman.

“I think I'll wait until later to bring Sammy, my four-year-old. He might freak out if he realises he's sharing me.”

Though his sons do not know he is a celebrity, Black admits they do ask questions when they see photographers waiting for them.

He said: “Well, we went to the park the other day and there were some creepy crawlers in the bushes with cameras. And Sammy said: ‘It's OK to take pictures in the movies, but not in real life.’ And I told him: ‘You're right’."
