The selfie Lopez shared on July 24 comes just days after she clarified that yes, her youthful glow is thanks to her own product line, JLo Beauty.

Jennifer Lopez just turned 56 and celebrated her birthday right in the middle of her Up All Night tour. And on top of slipping into a backless silver dress / partying with friends (while dancing to her new song "Birthday," naturally), J.Lo shared a bunch of photos to Instagram—including one without an ounce of makeup.

Jennifer Lopez wore a sparkly, backless dress that plunged all the way down to her butt to celebrate her 56th birthday. See her party frock, here.
