'Teen Mom' Kailyn Lowry Sizzles In Plunging Undies Upside-Down

Scroll for the latest photos – the above one made headlines last year as Kailyn wore only a Calvin Klein bra and jeans from Khloe Kardashian's Good American line to shut down mom shamers.

All undies today, posting with a range of looks from a cupped yellow bra and lacy black bralette to a boudoir reclining look while upside-down on a studded blue couch, Kailyn showed she's got what it takes, and the skimpy shoot definitely delivered. See her purple undies below!

Kailyn, shot lying down on the stylish couch, was having her blonde locks attended to by a masked crew member, with the Pothead haircare founder seen in only a tight, purple lace getup with long sleeves, a plunging neckline, and a minidress finish.

"@savagexfenty," Lowry wrote, shouting out the label just this month confirmed as worth $1 billion. Acting every inch the brand ambassador, Kailyn also encouraged fans to "Swipe up to get any of these looks from @savagexfenty," offering two bras for $20 when fans go VIP.

Kailyn, a mom to sons Isaac, Lincoln, Lux, and 2020-born Creed, didn't use a #ad in her post. The disclaimer required by Instagram doesn't appear necessary when a partner status is in place. Pay on the platform correlates with following, per Vox's experts:

"Influencers with up to 1 million followers can get $10,000 [per post], depending on the platform, and 1 million followers and up, you’re getting into territory where they can charge $100,000. Some can even get $250,000 for a post!"

Kailyn, who was massively trolled last year for having three baby daddies as she announced her fourth pregnancy, is coming into her own and having the last laugh. She's also sold her Delaware home, recently telling fans:

"This house is the physical manifestation of both the lowest and highest points of my life - the best point being Creed’s birth. I learned so much about myself and life in general through the extremes I experienced over the course of the year here."
