Ahh, yet another baby from The Hills. Heidi Montag and Spencer Pratt have finally joined castmates Audrina Patridge, Jason Wahler, Kristin Cavallari, Whitney Port and, of course, Lauren Conrad in becoming parents. The now-married couple had a famously up and down relationship that played out publicly on the reality-ish MTV show The Hills. And even though the pair have had their fair share of problems, it seems like everything is all-bliss with the birth of their first son!

Montag and Pratt welcomed their baby boy on October 1st, naming him Gunner Stone. Fans of The Hills might remember that the couple didn’t exactly see eye to eye when it came to having kids. Of course, that was years ago. While Heidi has been ready to get preggo since the day she said “I do” (at least, in theory), Spencer wasn’t on board.

Even though their reality show detailed the couple’s not-so-stable relationship, things eventually improved. Heidi showed off her love for her soon-to-be baby daddy while pregnant, posting on Instagram, “You are the best husband and I know you will be the most amazing father! We are so blessed to have you! Thank you for brightening up everyday of my life! I love you beyond words!”

Aww! Congrats to the new mommy and daddy!
