Lizzo is shaking what her momma gave her this Memorial Day Weekend … proving “Truth Hurts” but her curves heal — and flexing her Grammys ain’t bad either!

The singer-songwriter put her recent weight loss on Instagram Saturday … flaunting her bod in a tiny, layered bikini — and giving fans an ice pop-melting post to celebrate the holiday.

She also showed off her lyrical prowess by pairing the body-shakin’ post with a freestyle-type rap remix of Pluto and YK Niece’s “WHIM WHAMIEE” in which she sings … “I’ve been fat, I’ve been skinny / B****es still ain’t f***ing with me.”

The Grammy-winner — who makes sure to display her beloved Grammy trophies while twerking at one point — posted the bootylicious clip shortly after she shared an image of herself posing in a blue bikini while grabbing her chest.

The itsy-bitsy bikini appears to be the one layered under the yellow, snake print two-piece she rocks in her rapping video.

Fans are well aware Lizzo has been feeling “Good as Hell” ever since she started her weight-loss journey a few years back … thriving physically and mentally — and dancing her backside off with excitement!
