Beyoncé Knowles cannot wait for Christmas - because she gets to gorge on festive food.The 'Irreplaceable' singer also blasted Hollywood's current trend for super-thin actresses, insisting Christmas food is too delicious to miss out on because of a diet. She is quoted by Britain's Daily Star newspaper as saying: "People are obsessed with skinny girls at the moment. I'm going to be eating for America over Christmas to get some more junk in my trunk. So raise a glass and toast for me, people."The 25-year-old lost 13lbs in 10 days on a liquid-only diet for her role in 'Dreamgirls' but admits she has been having a good time re-gaining the weight. She said: "OK, I lost a lot of weight for 'Dreamgirls'. But I sure am enjoying putting it all back on."Beyoncé's gruelling diet - which saw her surviving on maple syrup mixed with water, lemon juice and cayenne pepper - sparked criticism from health experts, but during shooting the star warned other women not to copy the extreme eating plan. She said at the time: "In 'Dreamgirls', my character starts at 16 and then 20 years pass. Normally they'd change your make-up or your clothes but I wanted to go the extra mile. My nutritionist suggested the only way to do that was the fast. As soon as it was over I gained the weight back. I would never recommend it to anyone unless you are doing a movie."
