Bristol Palin has gone through quite the body transformation from her first time on Dancing With the Stars to now, and she's not afraid to show off her new body.. 

Strutting her stuff in little booty shorts and tall boots, the DWTS Season 15 All-Stars contestant and young mom was seen heading into the DWTS rehearsal studios in LA yesterday (September 30).

And what else was she rocking aside from a skin-baring outfit? A strikingly huge smile! It looks like Bristol's feeling good from the inside out. After all, the brunette star told Us Weekly, “I'm just more active and I cut all the crap out of my diet!" Well, it looks like the hard work is paying off.

What do you think of Bristol's rehearsal get-up? Is it too itty-bitty or should she be showing off her new bod? Let us know your thoughts in the reaction buttons below.
