Randy Houska Had An 'Explosive' Response To Daughter Chelsea's Pregnancy News

See what the ‘Teen Mom 2’ grandpa posted on Twitter

Chelsea Houska's dad Randy has been there for his daughter and granddaughter Aubree through thick and thin -- so naturally, when the MTV mama announced that she was pregnant with her second child (and first with fiancé Cole DeBoer), the Teen Mom 2 grandparent congratulated his offspring with a rather priceless message and complimentary photo on Twitter.

Understandably, Chelsea couldn't help but respond to Papa Randy's Snapchat screengrab with a simple "hahah." Pretty much sums it up!

In addition, shortly after the soon-to-be-DeBoers went up with simultaneous Instagram images featuring Aubree holding a sonogram of her baby brother or sister, Chelsea (who is due on Valentine's Day 2017) answered a bunch of fan questions during a Twitter Q&A. First up, what was the six-year-old's reaction when she learned about the new addition?

As for the peanut's gender, the couple is planning on finding out -- but does the family have a preference?

Meanwhile, many folks asked Chelsea if she would be postponing her wedding date (the bride-to-be had previously revealed that she and Cole would say "I do" in the fall):

Be sure to add your well wishes in the comments, then stay with MTV News for more pregnancy updates! And for an added bonus, watch the couple plan their wedding during the last season of Teen Mom 2!
