Megan Thee Stallion Flaunts Major Underboob in Green Bikini

Did someone say "SAVAGE?!" Megan Thee Stallion is back at it with a poolside bikini shoot, but her most recent pics take the cake -- they're "classier" and "bougier" than ever!

The rapper-singer is soakin' up some pool time -- captured with her short n' concise Instagram caption, "🌴✈️" ... she let all the hot shots do the talkin'!

Fierce and fabulous, check out this shot she slayed -- Meg posted up on the hot tub ledge and showed off her summer bod.

Hats off to you, Meg, the cardio, Pilates and strength training are paying off!
