He's Here! 'Teen Mom 2' Star Chelsea Houska Gives Birth To A Baby BOY With Husband Cole DeBoer — See The FIRST Photo!

And baby makes four! Teen Mom 2 star Chelsea Houska welcomed a baby boy with her husband, Cole DeBoer!

"Welcome to the world, sweet boy," the mother-of-two wrote. She gave birth on Wednesday, January 25th in the early morning.

This is the first child for Chelsea and Cole.

As fans may already know, Chelsea has a 7-year-old daughter, Aubree, with her ex-boyfriend, Adam Lind.

Back in December, Chelsea revealed how she felt completely different during her second pregnancy.

"With Aubree I was really young so I felt like I knew everything, which was ridiculous, but now I know so much and I’ve been researching everything and I’m just paranoid," she continued.

Throughout the pregnancy, Chelsea continued to update fans about the nursery, breastfeeding, and more!

Chelsea and Cole announced that they were expecting their first child together in the summer and exchanged vows in early October in an extremely private ceremony.
