It's almost 2014 and change is in the air! 2013 brought us amazing albums (shout-out to JT's The 20/20 Experience and HAIM's Days Are Gone) not to mention terrific movies like Gravity and Dallas Buyers Club. But the year has brought us more than music hits and film flicks that have kicked major butt... the year has also brought some unbelievable celebrity makeovers from start to finish.

From pixie haircuts to celeb slimdowns, it's been a whirlwind of unexpected look changes. Jennifer Lawrence revved things up with the highly anticipated Catching Fire, and now she's sporting a short look that's equally hot. Snooki worked her way to a sexier, more slender frame, and funny man Chris Pratt has done the same... and let me tell you, there's nothing funny about his sizzling hot new look. But don't take my word for it. Check out our full gallery to see the 20 stars who've decided to end 2013 with a bang and spice up their appearances. It's startling, jaw-dropping and totally amazeballs.
