The digital detective -- who is expecting his first child with girlfriend Laura Perlongo -- tweeted the exciting news, along with a candid article written by Perlongo about the pregnancy.
In addition, the parent-to-be also revealed the peanut's gender and reflected on this life-changing milestone.
"IT'S A GIRL!" Nev captioned the Instagram photo above of the couple at a doctor's visit. "No words can capture the excitement and joy I feel about becoming a father. I am so in love with you @el_peego and thank you for giving me this incredible gift. You inspire and excite me every day."
Fittingly, Max Joseph was quick to offer a sweet message to his brother from another mother:
Congrats, Nev! Better teach your little lady all about Google image search before she starts dating. Be sure to offer your well wishes to Nev and Laura in the comments -- and catch the mid-season finale of Catfish tonight at 9/8c!
