Sneaky! Bizarre Ways 'Teen Mom' Star Chelsea Houska Hid Her Secret Pregnancy Revealed In 6 Clicks

"And then there were four..." the 24-year-old mom announced on Instagram on July 12, hinting that her and hubby-to-be Cole DeBoer — who proposed to the redhead back in November of 2015 — were expecting!  

This will be the couple's first child together.  

<a href='https://okmagazine.com/photos/chelsea-houska-naked-instagram/'Chelsea's second pregnancy — she's already mom to 9-year-old Aubree — may come as a shock to some, given that she managed hide her baby bump from the cameras in the months leading up to her pregnancy announcement.

Aside from posting only sneaky selfies that didn't share the star's growing belly, the one full body picture Chelsea shared on social media had Aubree covering up her mama's baby bump.
