Jen Selter, social media's biggest starlet, added a racy shot on Twitter that shows off her curves while she takes a shower.

The photo that was posted on Thursday shows Selter in an outside shower as she wears a black bikini. She stands in a sideways back shot that flaunts her iconic booty as well as her strong legs. The water pours down on her head and through her body as it drips off of her.

Selter currently has more than 700,000 followers on Twitter and more than four million on Instagram. She became famous when she randomly started posting workout photos of herself, which gained a massive amount of popularity.

"I started posting motivating fitness pictures and quotes that got me up and wanting to work out," the model told People last May. "When I randomly added a photo of my own body, I saw a lot of likes."

One of Selter's most recent images on Instagram shows her doing a bridge pose near a body of water. As she sets her hand on a rail, she sets one foot behind her while the other foot kicks up in the air like she's doing the splits. This shot exposes the 21-year-old's muscular bottom torso along with the arch in her back.

This image is captioned, "Hope everyone is having an amazing day! Keep working hard toward whatever goal you've set for yourself #seltering."
