Photos: Super Shocking Celebrity Body Transformations

Celebs can shock us in many ways, but nothing is more shocking than a total body transformation. Here are some of the most jaw dropping looks. 50 cent's before and after pics dropped my jaws the longest, ok and maybe Jared Leto's! Whose did yours?

If we Re-e-wind back to 2001, Craig David was at the peak of his musical career. However, in 2013 he was clearly at the peak of his physical fitness. Wowza! 

Seemingly on a mission to prove he's no longer the little boy who sang catchy pop ditties, Justin Bieber embarked on a mission to beef up last year. He succeeded, but also looked a little funny!

Dwayne Johnson AKA The Rock has always been in tip top shape, but recently he's taken things to a whole new level. Look at those vipers!

Pint sized Jersey Shore star Snooki made it her mission to get into shape following the birth of her daughter. Thanks to many a session at the gym and a stint on Dancing With the Stars, Snooki has never looked better! 

When Geordie Shore's Vicky Pattison saw a less than flattering snap of herself in a bikini last year, she decided to take charge of her body - dropping from a size 16 to a size 8 

Despite saying she was embracing her fuller figure in 2012, Christina Aguilera transformed herself in 2013

Parks and Recreation funny man Chris Pratt revealed he got himself into shape by cutting out booze and hitting the gym - hard

50 Cent dropped from 214 pounds to 160 over the course of just 9 weeks through the aid of a juice based diet - all in the name of art!

Jared Leto always goes the extra mile for film roles - but even we were shocked when we saw this dramatic change for his role in Dallas Buyers Club. 

Celebrity Blogger Perez Hilton was more than willing to show off his weight loss/muscle gain last year. 

Nicole Richie first hit our screens back in 2003 with BFF Paris Hilton on The Simple Life. 11 years on and Nicole looks almost unrecognizable these days.
