'Teen Mom' Kailyn Lowry Rocks Tiny Top With Massive Hoop Earrings

Scroll for the photo. Kailyn, already a mom to sons Isaac, Lincoln, and Lux, welcomed yet another boy on July 28th, but this post wasn't about motherhood. The MTV face, whose Pothead haircare brand is a popular one, was shouting out her company, even offering fans a 35% discount.

The photo showed Kailyn indoors, by a circular wall mirror, and in a plunging and skimpy black top. The star, showing off gorgeous, free-flowing curls, also wore silver hoop earrings, with a bold red lip adding some glam.

Kailyn, also looking sideways and flashing those pearly whites, took to her caption, writing:

"Happy 2 year anniversary to my baby, @potheadhaircare 🎉 Today is the last day of our 35% off sale, use code BFCM at checkout until 11:59pm est!"

Kailyn, who also runs her "Coffee & Convos" podcast with Lindsie Chrisley, quickly racked up the likes, with fans telling her she's "killing it" – and she is. "Super proud of you!!" one fan wrote, adding that they've been watching "since the beginning." More snaps below.

Kailyn has had the chance to speak out about her brand. The blonde told Inked Mag that it started with her getting flattered.

“Well, I love my hair and I get a ton of compliments on it. So I wanted to get into the hair industry and I thought that CBD oil would be perfect to set me apart from other products," she said, adding:

"There are a lot of benefits to CBD oil and I figured that this was it. CBD oil is really good for your scalp and it makes your hair nice, shiny, and healthy.”

Kailyn isn't alone when it comes to "Teen Mom" cast members running businesses. Co-star Chelsea Houska has her fingers in a lot of pies, running her Lauribelles clothing collabs and Itzy Ritzy partnerships alongside her DIFF eyewear collab. The 29-year-old is also launching homeware brand Aubree Says.

Over on "Teen Mom OG," Mackenzie McKee runs her Body By Mac fitness brand, with former "Teen Mom" star Jenelle Evans last year launching her JE Cosmetics company. Fans are likely wishing Kailyn all the best.
