'Challenge' Cutie: Meet Jonna Mannion's Baby Girl

The MTV munchkin looks just like her mama

It's a real-ly exciting time in Jonna Mannion's life: The former Real World: Cancun resident just welcomed her first child!

The Challenge competitor -- who appeared on Rivals, Battle of the Seasons, Rivals 2, Free Agents and most recently Battle of the Exes 2 in 2014 -- is the proud mama of a beautiful baby girl, she sweetly shared on Instagram.

"Hey guys! My name is Naleigh J," Jonna added along with the photo above, featuring two scrumptious snaps of the newborn. "I was born about a week ago on 8/3 at 8lbs 14 oz. I am so excited to finally be home, happy and healthy with my mom and dad." Hopefully she's being "polite" and "real" toward her doting folks.

The brand-new parent also shared another heartwarming collage-style photograph with her eight-day-old princess.

J's friend -- and fellow vet -- Camila Nakagawa was actually the one to spill the beans about the mini Mannion in May. Now, we're looking forward to seeing Baby N with her MTV aunts and uncles -- or playing with some petite guys and gals from the Real World and Challenge family!

Offer your congrats to Jonna on her brand-new addition in the comments!
