Nicole Richie
The reality TV troublemaker turned fashion designer and two-time mama not only turned her life around but also changed her figure (a couple of times). The gal slimmed down to a gawk-worthy thin frame and more recently put a few pounds back on.
Britney Spears
Just call her Mrs. She's Too Big Now She's Too Thin. The much talked about pop star (and mom to two) let her weight yo-yo through the past few years but recently toned her infamous tummy for her Femme Fatale world tour.
LeAnn Rimes
If you believe the country crooner's Twitter bitchin', she's sporting a super fit beach bod complete with six pack abs. But anyone who's compared pics of the broad's bikini bod can see that she has shed some serious weight.
Kate Bosworth
While Alexander Skarsgård's ex-lady friend used to get picked on for her stick-like figure, the red carpet cutie has taken to the beach more recently to show that she's filling out her itty bitty bikini with a (little) bit more meat on her bones.
Jennifer Hudson
Talk about a transformation! The former American Idol songstress (and Oscar winning Dreamgirl) moved on from a year full of tears by slimming down and flaunting a brand new beach-ready body worthy of a little gold statue of its own.
Kim Kardashian
The bride-to-be has always been a curvy chick, but has taken to Twitter to tweet a few pics of herself that clearly show she's dropped a few pounds, leaving people wondering if it was courtesy of a tough gym routine or a serving of QuickTrim.
Jordin Sparks
Nothing says "Look at me now!" better than a Twitpic. Which is exactly why American Idol winner Jordin Sparks flaunted her slimmed down self in a polka-dot two piece for all of the World Wide Web to ogle.
Kelly Osbourne
The rockstar daughter and fashion correspondent hasn't been shy when it comes to talking about (and showing off!) her taunt tummy and trimmed down legs. Thankfully, her stylish new image still comes with a dose of her trademark sass.
Tyra Banks
The America's Next Top Model mogul and former talk show host used to flaunt it on a runway for Victoria's Secret, but now she's sporting a different shape poolside for the paparazzi.
Gerard Butler
Gone are the days of his 300-like abs, but our token guy in this gallery has gone through a few different beach bods of late. For a while, Gerry had packed on the pounds but recently dropped quite a few and packed on the muscle instead.
