The singer has cut out the carbs and instead opts for tasty portions of sushi - not burgers and frappucinos. She exhibited amazing energy and was in great shape - her body looked better than it has in years, GK Reid - who recently styled the music video shoot for Spears hit new single, 3 - told the New York Post newspaper. She munched on sushi instead of junk food, and even sang live with the words. She worked really hard and was really sweet to all the dancers. At the beginning of the month, Spears, 27, splashed out a whopping $3,000 on candy. She spent about $3,000 and walked out of the store with 10 bags, revealed a source. She got a bunch of candy and shirts for her kids and got a bunch of the couture lollipops to give to her back-up dancers. -Showbiz Spy
