"I'm glad I re-signed [with Jenny Craig] because I had a little fun over the holidays, as most people do," says Latifah, 38, who announced this month that she would continue as the spokesperson for the weight-loss program.
"I went to Trinidad and I indulged in everything," she says, admitting to falling off the wagon temporarily while on vacation. "It wasn’t that I wasn’t eating healthy stuff. It was just a lot of it. There's always a beach barbeque."
But she is putting the chicken stews and the rum punch away to get back to "a size healthy." Working out regularly and swimming, she's confident: "I will knock this weight back down. I know it," she says.

As for Latifah's particular pick at the ceremony, she cites The Dark Knight's Christian Bale, who is nominated five times, including Favorite Superhero.
"I've got a crush on him even though he's married with kids, but he is a hot piece," she says.
Others sure to be delivering punchlines at the event: Adam Sandler and Robin Williams. "Who know what his crazy behind is going to say or do," says Latifah.
