Jan. 17, 2016, was a transformational day for the women of MTV's Teen Mom franchise. Three of those reality stars — Teen Mom 2's Kailyn Lowry and (http://www.intouchweekly.com/tags/teen-mom-3-11946) sisters Briana DeJesus and Brittany DeJesus — all went under the scalpel that day in Miami for plastic surgery procedures. And luckily for curious fans, their surgeon spilled all the details.

"Kailyn had a Brazilian butt lift and a tummy tuck," Dr. Michael Salzhauer aka Dr. Miami told People. "Briana had the Brazilian butt lift, labiaplasty, and breast implant exchange — she had implants, and she wasn't happy with them, so she went a bit bigger. And Brittany had a Brazilian butt lift and fat transfer to the breasts. She didn't want implants. She wanted a more natural augmentation."

Apparently, Brittany approached the doc first, and when Kailyn contacted him later, he scheduled all three of the reality stars for the same day. "All three girls had different issues with their bodies that they'd been dealing with, and really there is no way to improve what they wanted to improve through the gym," he said.

This Dr. Miami dude also dismissed criticism that the Teen Mom stars were too young for these kinds of changes. "People look at women in their early 20s having plastic surgery and they say, 'Oh, they're too young for that,'" he said. "But really that's not true. It's not about age. It's about what has your body been through and what can we do to improve it. If you have kids when you're a late teen and you're done having kids, at least for a while, you pretty much missed your whole teenage years."

With their nips and tucks crossed off their to-do lists, all three women then continued their reality careers. Kailyn has starred on Teen Mom 2 since day one; Briana decamped to Teen Mom 2 once Teen Mom 3 was canceled; and Brittany just got her own special, Being Brittany.

Briana even returned to Dr. Miami earlier this year for another "Mommy Makeover." And though then-boyfriend Javi Marroquin was there by Briana's side, he apparently didn't appreciate her Snapchatting the surgeries, and they ended their relationship shortly thereafter. Well, let's hope she's at least happy with her physique now!
