Leave it to Jennifer Lopez to make Self-Care Sunday straight up sexy.

Yesterday, the singer, actress, and JLo Beauty founder took to Instagram to show off her insanely enviable physique. For a casual mirror selfie, Lopez wore a super high-cut, bright-white swimsuit with a plunging neckline while sitting atop her legs. Lopez kept the rest of her look minimal, opting for her signature oversized gold hoop earrings as her only accessory; wearing her hair in a chic, messy top bun; and going with natural-looking makeup.
