TEEN Mom star Briana DeJesus has undergone a major body transformation through the years with the help of plastic surgery.

The star has spoken openly about her procedures, even documenting some via social media.

Briana started her MTV journey as a student in high school preparing to welcome her first child.

She's grown up and changed a lot since then, but not all of that change has been natural.

The reality star has spoken openly about going under the knife, which she did for the first time back in 2016.

She has had several other procedures since then, totaling more than $67,000 in plastic surgery.

Briana has had three boob jobs, a Brazilian butt lift and other surgeries.

Many fans claim she looks totally unrecognizable from her early days on MTV.

Her look continues to evolve, leaving fans stunned with each tweak.

Here's a look at Briana's changing appearance through the years.

2016

In 2016, Briana underwent a mommy makeover after giving birth to her eldest daughter Nova back in 2009.

She got her first of several breast augmentations as part of that procedure, which included surgery to plump up her butt among other things.

When she was first introduced to MTV viewers, Briana was quite thin and had very small breasts.

In the years since she's made a habit of showing off her ample curves.

2018

Briana went under the knife again two years after that surgery after noticing changes in her body following the birth of her second child, Stella.

She got her second breast augmentation at that time.

The procedure, done by Dr. Miami, also included a tummy tuck and reshaping and contouring of her butt.

After the surgery was done, she took to social media to show off the results.

At the time, she tweeted: "18 days post op! Progress!!!!! Can't wait to hit the gym next month."

She then posted another photo of her chest and stomach, writing: "No more big boobs either."

Briana was dating Kailyn Lowry's ex-husband Javi Marroquin prior to the surgery, but the pair split over differences related to the procedure, among other things.

"Javi and I are not together anymore," she said at the time.

"Our future just doesn't line up. He doesn't want me to get my surgery for a breast lift, lipo, and tummy tuck (which I'm doing in two weeks) because it'll look bad on his name at work. Also, I don't plan on moving in with him in the summer and for these reasons, he broke up with me."

After her procedure back in 2018, her surgeon told E! News, "I did a tummy tuck, a breast lift with an implant exchange because she did have implants from before.

"She wanted to be smaller, higher and perkier - so we changed her implants out for smaller ones."

2020

Briana visited Dr. Miami for a third time in 2020.

She took to social media to show off her body rocking a pair of biker shorts and a tiny white top.

She told In Touch magazine ahead of the procedure: "I just want to start a healthy life and gain my confidence back.

"Bigger is not always better. Plus, my back is always hurting.”

Following the surgery, Briana kept her fans updated on her progress.

She tweeted in early February: "Hey guys! I am doing great. I feel so good."
