She's come such a long way! We first met Alexandria "Alex" Sekella on 16 and Pregnant in April 2012. She was struggling with a near-impossible situation: being a pregnant teen that wanted to keep her baby when everyone else in her life was telling her not to. Her drug-addicted boyfriend Matt McCann wanted nothing to do with baby Arabella, and her mom Wendi said that unless she gave Belly up for adoption, she wasn't welcome to stay in her home.

But Alex knew she needed to keep her baby, so she did! We caught up with Alex one year later on MTV's short-lived Teen Mom 3. Her mom eventually caved and let Alex stay with her, and when her boyfriend got out of rehab, he moved in too. Unfortunately, that didn't work out. The couple came to near-blows on multiple occasions, and Alex's mom asked Matt to move out. At the end of the season, we learned that Alex didn't have enough credits to graduate from high school, but her story didn't end there! The show may be over, but Alex has persisted, and now she's living a happy adult life at 24 years old!

Alex is obsessed with her daughter, who turned six years old on July 18, 2017. "My how big she has grown, from the day she came home all the way to today," wrote Alex on Instagram. "I love her so much and I can't picture a single day without her." And of course, Wendi loves her granddaughter and has grown very close with her daughter after the show. "Happy birthday to this awesome mom," wrote Alex for Wendi's birthday. "She helps to make me the mom I am today."

Alex has a new man in her life, and he loves Belly like his own child. His name is Tim Peters, and they've been together for almost four years! They celebrated their three-year anniversary in April 2017, with Alex writing, "Another year added to what is hopefully going to be many more in our future. Happy anniversary to this amazing man who has done so much for me."

If you're hoping to see Alex on another iteration of Teen Mom, don't hold your breath. "I'm sure when the discussion about pulling cast members from Teen Mom 3 for Teen Mom 2 my name was probably not even mentioned because they knew that I did not want it," she explained in 2017. "Honestly though that was the best decision I could of made. I've been able to start a normal life and start a REAL career that will last a very long time and benefit my children. I've also been able to find a real relationship that won't be picked and prodded at by the world to see. I have had a pretty drama free life since the end of teen mom 3 and I don't believe that any of that would've happened if I had not removed myself." Congrats girl, keep doing you!
