Jenelle Evans Has Added A Brand-New Member To Her Family

And it's not baby #3!

It won't be long before Jenelle Evans welcomes a girl into the family fold -- but before her first daughter makes her highly anticipated debut (at the end of January!), the Teen Mom 2 star is integrating a special someone into her clan. A hint: This little lady will let out a few barks...

"Thanks so much to @johnny_platinumgotti for our newest little family member!" the 25-year-old captioned the photo above, which features her beau David Eason and son Kaiser bonding with their brand-new pooch. "Our family adores her and our other Pitbull is in love. #DogLove #PitbullsOfInstagram #HomeSweetHome #Gottiline #Exotic."

While Jenelle didn't divulge the dog's name -- or how she is adapting to life with her gang -- the trio certainly looks like they are adjusting nicely to the pup.

Offer your congrats to Jenelle on the cute canine in the comments -- and be sure to stay with MTV News for more pregnancy updates before Baby Ensley's arrival!
