The MTV star -- who welcomed daughter Cleo James with fiancée Laura Perlongo less than a week ago -- shared a sweet photo of his snoozing newborn, with three heart eyes emojis as the caption.
It's easy to understand why he feels like the "happiest man on Earth": Baby C's delicious little paw is adorably grasping his fingers -- and looking as peaceful and lovely as ever during the innocent moment. Next milestone event on the horizon: Halloween. Now we can't wait to see this kiddo's ensemble, since Nev and Laura absolutely nailed decorating the belly.
Be sure to offer your congrats to Nev and Laura -- and stay with MTV News for more C-squared (Catfish and Cleo!) updates.
