Last night, Karrueche, her BFF Christina Milian, the [rumored to be] newly-single Tiny and a handful of other ladies got their workout on in a sexy way, hitting up a ‘twerkout’ class in L.A. to shake their booties and shed some calories! With twerking being all the rage, these kinds of classes are actually becoming quite popular, as there’s actually a technique to perfecting the twerk – and you can really get a good workout while doing so. Check out pics from last night’s class in the gallery, and get more info on the class they took here.
