LOS ANGELES, CA  [Friday May.18.2007]  /Mix103FM.com/ -- Beyonce Knowles has admitted it was tough keeping her figure in check while filming the hit movie "Dreamgirls," and blames it all on pork skins.

The "Irreplaceable" star went to great lengths to lose weight prior to shooting the film, but according to Teenmusic.com, that all went out the window once she got on set.

Knowles said, "It is so tempting on film sets."

"They have these tables with every kind of food. I'd eat pork skins because that's the closest thing to chips."
