Paige VanZant Flashes Major Underboob In Neon Bikini!

Paige VanZant's not fighting in The Octagon anymore, but she's certainly drawing people in with her spheres ... showing some serious cleavage in these new bikini pics.

The former UFC fighter shared a series of photos where she's decked out in the tiny neon orange 2-piece ... pulling on the string connecting the two cups of the thin material and puckering up her lips as she poses for the camera.
