It's been over a year since Kailyn Lowry and Javi Marroquin got hitched in a simple courthouse ceremony on Teen Mom 2, and she's finally taken a huge step in their married relationship! After a year of being "Kailyn Lowry" on social media, this blonde bombshell has officially changed her Twitter handle to Kailyn Lowry-Marroquin. It's all happening, people.

We assume that Kailyn legally changed her name directly after her wedding ceremony, but let's be real — these things aren't official until they hit the internet. By the way, we love that Kailyn opted to hyphenate her and Javi's last names rather than completely forsaking her own. What a feminist! No word yet as to whether Javi also changed his last name to "Lowry-Marroquin," but according to Twitter he's sticking with his original moniker.

Are you surprised that Kailyn hyphenated her last name rather than nixing Lowry in favor of Marroquin? This gal doesn't exactly have a close relationship with her own family (she hasn't spoken to her mom for months!), but her last name is just as much a part of her as Javi's name is part of him. Girl power, guys! Time to burn all our bras.

Oh, and when it comes to Kailyn's kids, it looks like she's perfectly fine letting them take the last name of their respective fathers. Isaac's full name is Isaac Elliott Rivera and Linc's full name is Lincoln Marshall Marroquin!
