Chelsea Houska of 'Teen Mom 2' gives birth to baby boy

Jan. 25 (UPI) -- Chelsea Houska has given birth to a baby boy.

The 25-year-old Teen Mom 2 star announced Wednesday on Instagram that she welcomed a son with husband Cole DeBoer.

"Welcome to the world, sweet boy," she captioned a photo of herself holding the newborn's hand.

Houska is already mom to 7-year-old daughter Aubree Lind with ex-boyfriend Adam Lind. She announced in July that she and DeBoer were expecting their first child.

"We are beyond excited for this journey and can't wait to share it with you all!" the star wrote at the time. "Big sister Aubree is also extremely excited."

The Teen Mom 2 star later told fans she was expecting a baby boy. She said in November that she and DeBoer were "so excited" to add "a little guy" to their family, and that "his little closet" was "already filling up with plaid."

"Cole is the PROUDEST man I have ever seen, and cannot wait to have his son. He's already planning his future hunting and fishing trips, haha! Thank you guys for always being so supportive of our family!" the television personality wrote.

Houska's co-star Jenelle Evans also welcomed a baby this week -- daughter Ensley Jolie with fiancé David Eason. Evans is also mom to 7-year-old son Jace Evans with ex-boyfriend Andrew Lewis and 2-year-old son Kaiser with ex-fiancé Nathan Griffith.
