Looks like we may learn the identity of Kailyn Lowry’s baby daddy once and for all!

According to a new report by The Ashley’s Reality Roundup, MTV is “desperate” to get the man who fathered her third child to appear on the upcoming season of Teen Mom 2! A crew member tells The Ashley that, so far, he has refused to sign a release to be filmed — and the “mystery man” has even be around while Kail has filmed, but they opt not to show his face as they don’t have the clearance to do so.

Not much is known about Kail’s baby daddy, though a rep for the mom-of-two said that he’s a man she “briefly dated.” Earlier this week, she slammed rumors suggesting she doesn’t know who got her pregnant.

While Kail — who is mom to seven-year-old Isaac and three-year-old Lincoln, with exes Jo Rivera and Javi Marroquin, respectively — hasn’t identified her baby daddy, many fans believe that it’s her friend Chris Lopez.

Chris first sparked rumors when he tweeted about his “miracle child” in a tweet favorited by Kail. After announcing her pregnancy, she may have let his name slip during an Instagram Live session, during which she asked for baby names. When one fan suggested “Holden,” Kail said she liked it but worried “Chris” would make silly jokes like, “I’m ‘Holden’ the baby.” The final hint came when she shared a picture of her baby bump, and labeled it “Baby Lo.”

Curious who else has been named a potential baby daddy?!
