Kim Kardashian's ex-assistant, Stephanie Shepherd, didn't just leave her old gig with a sweet resume ... she left with a whole lot of experience in the hot body department.
Steph was in Miami for Art Basel over the weekend where photogs got her stepping out of the pool in a black bikini ... with her cheeks on full display. You can't help but think ... Steph learned at the foot of the master.
She and Kim parted ways amicably in September, and from the looks of these pics it looks like Steph has put it all behind her. Well behind her.
