Britney Spears has undergone some major changes to her appearance since beginning her residency at the Las Vegas Planet Hollywood last year.
First, Britney's super blonde hair had fans wondering if she was sporting a wig, now the National Enquirer reports that Brit has packed on the pounds in recent months - and friends are starting to grow concerned.
"Britney has gained close to 30 pounds and she's got a lot of cellulite on her legs and stomach," says a source close to the singer. "to disguise her belly on stage, she wears a one-piece leotard made out of a shaping material for a slimming effect."
"She also uses tanning beds and spray tans to hide her cellulite but it looks ridiculous."
If this report is true, Britney's bloat must have happened quickly, as Spears' bikini photos from March of this year show the 32-year-old mother of two looking trimmer than ever.
But friends say it's a pattern she's repeated her whole life. When Brit gets stressed she turns to her favorite vice: fast food.
"Britney isn't using her home gym and she's gorging on junk food," says the insider.
"She loves McDonald's and Taco Bell, and she's eating tacos, corn bread and fried chicken. She also drinks Cokes and fatty frappuccinos from Starbucks."
Give her a break, source! Britney's playing nightly shows at a hot spot for aging Midwestern tourists - she's just trying to connect with her fans!
