Jenner also showed off her fit figure in boyfriend Travis Scott's new music video for his song "Stop Trying to Be God."

In it, the 20-year-old plays a Virgin Mary-like figure. Jenner is seen in two scenes while her body is covered in gold paint — one when she’s comforting Scott after he was engulfed in flames and another when she’s wearing a sequined gown while holding a lamb.
