It’s fast approaching! Teen Mom 2 star Chelsea Houska is pregnant with baby No. 4 and her bundle of joy with husband Cole DeBoer will be here before we know it. But when is the reality starlet’s due date? Here’s what we know.

“One more DeBoer! Coming early 2021,” the 29-year-old captioned a photo of the family’s names written on a piece of wood to commemorate the milestone on August 5. The MTV star noted the baby would arrive in early 2021 — which would make sense based on the couple’s gender reveal celebration.

Chelsea and Cole, 32, announced their baby’s sex — it’s a girl! — to the world on August 7, though the 16 and Pregnant alum revealed the celebration took place a few weeks prior to her sharing the images. Parents typically reveal the sex of their babies between 18 and 21 weeks … which would put baby No. 4’s due date right around the first week of January 2021.

The mother of three shared her first baby bump photo and a sweet update on her pregnancy on August 6.

“I’m so excited to share this whole process with you and I swear I already have a bump and I’m fairly early but I guess when it’s your fourth baby it just be poppin’ right away,” Chelsea gushed on her Instagram Stories. “But anyways [sic], I just want to thank you guys it seriously means so much to me that you guys are all so sweet and you care about our family so thank you thank you.”

The TV personality and her hubby started dating in 2014 and tied the knot two years later. The couple welcomed their first child — son Watson — in 2017. Their daughter, Layne, 23 months, was born the following year. Chelsea is also mother to daughter Aubree, 10, whom she shares with ex-boyfriend Adam Lind.

While Cole is close with all of his children, he shares a special bond with his stepdaughter. He was even Aubree’s date to her Father-Daughter dance in 2019. “I am very proud of who this sweet girl is becoming the older she gets!” the proud papa wrote on Instagram at the time. “I swear she is already an adult.”

We can’t wait for baby No. 4 to join the mix!
