DITCHES THE DIET

Britney Spears is sick of being a slave 4 her diet. With her latest tour wrapped, the pop star is letting loose — but her fitness freak boyfriend, Sam Asghari, is worried she’ll fall off the wagon and into a pile of Cheetos! “This is the first time in years that Britney’s not worked out at least once a day,” titters a tipster. “Sam is still hitting the gym hard, but Brit is kicking back.” And digging in! “It’s no secret that Britney loves fried chicken, pizza and chips, and she’s having it all,” titters a tipster close to the 36-year-old blonde. “She swears she won’t go berserk, but Sam doesn’t want her blowing all her hard work on a few too many Frappuccinos!”
