Julia Gilas — Babe of the Day

It's her duty to flaunt that booty.

When it comes to bodacious buns on Instagram, it's no secret that Julia puts the "ass" in "Gilas." Wonky wordplay aside -- she has one of the most recognized rears on the image-driven social media platform. Gilas has nearly 5 million followers eagerly awaiting her next fire image to hit their feed, which is a pretty regular occurrence because all of her images bring the heat.

Julia is a fitness trainer and her Insta description says "get in better shape." She must be talking to you, because her "shape" already looks perfect to us.
