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 over 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.
