"Catfish" host Nev Schulman is officially a father, and make no mistake about it, he is beyond thrilled.

The new dad took to Instagram after his fiancé, Laura Perlongo, gave birth to their newborn daughter to share his glee.

"Best. Thing. Ever," he captioned an Instagram picture of him holding his newborn daughter. "Cleo James arrived at 6:01am weighing 6lbs 10oz. Shout out to my baby mama @el_peego for delivering this bundle of joy."

Nev is shirtless in the image while his little girl wears a tiny pink hat. Cleo is also wrapped in a blanket and looks up curiously at her father.

Cleo's ecstatic mother also shared a beautiful image on Instagram of her new family.

"I don't remember this photo being taken or anything about the last 24 hours but bb girl has finally arrived," Laura captioned an image of her newborn resting on in the hospital bed as Nev looks on smiling. "Completely enamored with 6lb 10oz Cleo James born this morning at 6:01. She's everything."

The MTV star shared a little more on Facebook, revealing that Cleo was born at the NYU Langone Medical Center.

"I am speechless. No words can express the complete joy and total awe I feel for my beautiful partner and the tiny angel we created." he wrote. "I've never been so in love. Little baby Cleo and momma are both happy and healthy and doing great."

The couple had fun though out the pregnancy, often dressing up Laura's belly to fit the background. Last week, at a pumpkin patch, she drew two eyeballs on her stomach and fit her belly into a cutout of farmer so make it appear like the face.

Last week, Nev shared an image of Laura in the tub in which they turned her baby bump into an island, resting palms trees, a small sand castle and a pair of flip flops on it.

"Baby's due any day now! totally obsessed with this woman but definitely going to miss this adorable baby bump. @el_peego #wcw," Nev said.

Congrats!
