Hot mama! Teen Mom alum Kailyn Lowry dropped jaws with her bikini body while on a tropical vacation to celebrate turning 33 years old. Many fans were impressed by her swimsuit figure after having seven babies.

Kail, 33, rocked a black two-piece while standing on the beach in Turks and Caicos in a carousel of photos she posted on March 14. The Pride Over Pity author tugged at the sides of the bottoms while showing off her tight tummy in front of the blue sea.

“How … HOW HAVE YOU HAD 7 BABIES. I’ve had none and cannot compare. You go girl!!!” one fan gushed in the comments, while another asked, “7 kids? Where? You’re stunning.”

“Wow you look absolutely incredible!! You are glowing,” a third follower told Kailyn, while a fourth wrote, “Can we just talk about how amazing you look!”

In addition to the bikini photo, the former MTV star showed off her flat tummy in a black tank top and shorts while on an ATV outing with fiancée Elijah Scott, who joined Kail for her birthday getaway. She also posted photos showing off other glimpses of her trip, which included a piece of chocolate birthday cake with a bottle of red wine, a snapshot of her vacation read — which was author Freida McFadden‘s new book The Tenant — and her lunch of tacos on the beach.

It appeared to be a couples’ only getaway for Kailyn and Elijah, 26, as their three young children and her four older kids weren’t shown in any of the pictures.

The duo welcomed 2-year-old son Rio in November 2022, followed by the birth of 17-month-old twins Verse and Valley in October 2023.

Kailyn gave birth to her eldest son, 15-year-old Isaac Rivera, with ex-boyfriend Jo Rivera in January 2010. She welcomed son Lincoln Marroquin, 11, with ex-husband Javi Marroquin in November 2013. Kailyn and ex-boyfriend Chris Lopez share two sons: 7-year-old Lux Lowry — who was born in August 2017 — 4-year-old Creed Romello Lowry-Lopez, whom the former duo welcomed in July 2020.

The Pothead Hair Care founder confirmed her engagement to Elijah during the August 22, 2024, episode of her “Coffee Convos” podcast. Cohost Lindsie Chrisley pointed out a diamond ring on Kailyn’s finger, causing her to admit they were getting married.

“I couldn’t really make an announcement [about it] because I couldn’t really give you a time that he asked me to marry him,” Kailyn explained. “It was just like, ‘When are we going to get married?’ It was, like, asking me to marry him all the time. And then one day he showed up with a ring.”

“[Elijah and I] have both been married already, so we both don’t care about the whole, ‘get on one knee and make it all romantic and stuff,’” Kailyn told Lindsie. “Because that’s just not how we are.” As for how the “casual” proposal went down, she explained, “He came into the bathroom one day while I was getting ready and he gave me the ring. I was like, ‘Oh my God, thank you!’”

As she embraces life as a mom of seven with Elijah by her side, Kailyn tearfully discussed getting a breast reduction and liposuction during an Instagram video on January 7.

“I think a little nip and tuck in terms of a nose job or a boob job is OK. But to go through this to be skinny is mental illness truly. And I say that with the most respect to anyone going through it,” Kailyn confessed.

“I was going for a breast reduction then I was like, ‘You know what, I should just add some lipo 360, add some tummy tuck in,” the reality star said of her recent procedures, even though she said her old tummy tuck scar and C-section scars “were fine.”

Kailyn had one last piece of advice before signing off, telling fans, “Think once think twice before you get plastic surgery, and I hope everyone has a happy new year.”
