Beyonce Knowles has admitted that she is relieved to be putting some weight back on, after shooting the film Dreamgirls.

The singer had to lose 20 pounds for her role in the movie, in which she plays Deena Jones. And now Beyonce, who is not comfortable with the image of many thin women, insists she is ready to put on the lost weight over the holiday period.

"People are obsessed with skinny girls at the moment," she told the Daily Star. "OK, I lost a whole lot of weight for this movie but I sure am enjoying putting it back on."

"I'm going to be eating for America over Christmas to get some more junk in my trunk," she laughed.
