Congratulations are in order for one of Teen Mom's most memorable couples.
Catelynn Lowell and Tyler Baltierra welcomed a beautiful and healthy baby girl New Year's Day. And as it turns out, Teen Mom 2 star Kailyn Lowry was the one to spill the beans.
"Congratulations to my good friends @CatelynnLowell and @TylerBaltierra," she tweeted. "Cannot wait to meet your new bundle of joy." Tyler replied with the message, "Thanks Kail! Can't wait for you to meet her either!"
The engaged couple put their first child, daughter Carly, up for adoption in May 2009 and allowed America to witness the emotional process through MTV's 16 and Pregnant.
More than five years later, both reality stars believe they are absolutely ready to raise a child on their own.
"I am an adult and I can tell when I'm ready," Catelynn tweeted shortly after her pregnancy news broke. "idc what ANYONE says I'm gonna do me! We ARE READY for a baby.
Tyler echoed his fiancée's sentiments by writing, "Yeah I want a baby, so what!? I have been through enough in my life to understand the wisdom it takes to make this decision
As they welcome a new family member, the twosome also appears to be more in love than ever before.
Just last month, Tyler reaffirmed his love for Catelynn by gifting her a brand new engagement ring on Christmas.
"She's the best thing that has ever happened to me," Tyler wrote on Instagram just before the holidays. "She's everything I want that I never knew I needed. She's the most selfless, kind hearted woman that I'm lucky enough to call mine."
And while the twosome is more than excited to welcome another child, both Tyler and Catelynn can't help but think of Carly often.
"Thinking of my daughter A LOT!" Tyler shared on Facebook the same day he revealed the gender of his second child. "I wish she could be here to share the joy of today with me #Bittersweet #SacrificeNEVERstops."
Congratulations to the happy couple on their baby news!
