Rumer Willis Bends Over In G-String With Explicit Caption

Scroll for the photos. While half of celebrity Instagram shouts of 25-year-old rapper Stallion via "WAP" or latest "Body" track, Rumer was going for the Texan's OG moniker – Megan Thee Stallion is, of course, a "hot girl" who does "hot girl sh-t."

Proving two can play at this game, the actress posed on her knees and on a bed while in cupped yellow undies as she showed off her stunning figure and rock-hard abs, then taking it a little sportier with a swipe to the right.

Rumer, knocking the camera dead with ethereal beauty and looking very much like mom Demi, then took it outside the bedroom and by a fireplace for a lean forward and in black lingerie. The star looked downward as she leaned against a record player, showing off her super-peachy booty and toned legs, also writing: "2021 hot girl sh-t=loving yourself."

Rumer is fresh from a massive clap-back as she defended updating her Instagram in skimpy undies, and the daughter to superstar Bruce Willis didn't hold back.

The "Dancing With the Stars" alum, in promo mode for Cuup, told the lingerie brand: "There is all of this shame attached to becoming a woman, but, at the same time, there is so much emphasis on quickly mastering beauty and sensuality," adding:

"Suddenly, there are all these checkboxes: your face, your teeth, your butt, your boobs. If you are desirable within these checkboxes, if boys like you for these things, then you are valuable."

Rumer, who stated she doesn't owe anyone an "explanation" for her "personal choices" as she posed on a floor rug in revealing underwear, added that her self-acceptance journey hasn't been easy, saying it was "absolutely something that is still a work and progress and something I still struggle with daily."

Rumer's post did catch some celebrity attention, gaining a like from "Big Bang Theory" actress Kaley Cuoco's little sister Briana. "The Flight Attendant" star was also joined by gymnast Nastia Liukin in leaving a like.
