Teen Mom’s Kristina Shirley reveals weight loss in bikini for rare new pic as stepdaughter Leah pays tribute to ‘momma’

TEEN Mom star Kristina Shirley has given fans a glimpse at her impressive weight loss after slipping into a bikini.

Kristina, who is married to Gary Shirley, was snapped alongside her stepdaughter Leah while wearing a black two-piece swimsuit.

The slimmed-down star, 38, was also wearing dark sunglasses and cuddled up to Leah for the sweet selfie.

Leah, 16, posted the picture on Instagram alongside a series of photos to celebrate her stepmom's birthday.

In a gushing tribute, she described Kristina as her "momma" writing, "Happy birthday momma! I love you so much❤️ @kristina_shirley3."

Fans were quick to comment on the post by Leah, whose birth mom is Teen Mom OG Amber Portwood.

Many took her words as a diss to Amber, who Leah doesn't speak to.

One fan replied, "I love the fact Leah calls her Momma ❤️❤️."

Another added, "Happy birthday, Momma!! 🎂❤️ You are the definition of a Momma..and your relationship is..ABSOLUTELY BEAUTIFUL!"

A third said, "Happy birthday to your beautiful mama! I’m so happy you have each other! She is lucky to have you sweet Leah!"

And someone else chimed in, "I absolutely love seeing this. Seeing how much you love her and seeing how much she loves you. She’s everything you need 💕."

Kristina appeared a little overwhelmed with Leah's post and the kind words from her followers.

Thanking them, she wrote, "Thank you to ALL of you for your kind words, wishes, love and support!! Thank you @itsleahtime12 for being part of my special day and baking my favorite cake! I love you more! 💜 🤍."

Kristina and Gary first debuted their dramatic weight loss transformations during the Teen Mom: Next Chapter reunion.

The couple, who share their 10-year-old daughter Emilee, have continued to work hard at shedding the pounds.

Kristina does, however, keep a low profile on social media so fans are rarely able to congratulate her on her efforts.

Weight loss secret

Last summer, she showed off her slimmed-down figure in a pair of tight biker shorts and a tank top at a shopping event.

Kristina was pictured alongside Leah and Emilee and her followers were impressed with her transformation.

One follower asked, "You look fantastic," before bluntly asking, "Did you have surgery?"

Kristina replied, "Thank you!! No, I did not have any surgeries. Eating healthier and working out."

"So proud of you for being healthy!!" commented another fan.

Meanwhile, in March we told how Leah's mom Amber was rumored to have been fired from Teen Mom: The Next Chapter.

Despite being an OG since the original season of the show in 2010, she only made a short cameo this year.

Amber later hit out at the whispers in a TikTok Live and insisted she had quit the show for her mental health.

"Not only am I not being let go, I quit three days ago,” Amber said.

“I told Larry, the producer, I quit. My mental health was one of the things I said other than the yelling and crying from being so damn hurt from stuff.”
