Actress Jessica Alba says she is strict with her diet.

The "Sin City" star, who has daughters, Honor, six, and Haven, three, with husband Cash Warren, says she only enjoys treating herself occasionally as she likes being in good shape, reports contactmusic.com.

"I don't indulge too much. I mean, I love desserts and stuff, but I don't think that's very sinful," said the 33-year-old.

"I love nachos so much! And tequila," she added.

Alba toned up for her role in the upcoming sequel by dancing.

The star who has an enviable figure, hates exercising as she finds it "boring".

"I hate working out. It's boring! I really only did it when I had a job that was physically demanding. But from age 17 until I was 27, all I did were movies that were physically demanding -- so all I did was work out all the time!" she said.
