STAGE TUBE: Diaper Challenge is On For Cast of ABC Family's BABY DADDY

Cast members Jean-Luc Bilodeau, Derek Theler and Tahj Mowry of the new ABC Family series BABY DADDY competed in a diaper changing competition. Luckily, the less-than experienced diaperers used a baby doll instead of the real deal! See who comes out on top below!

"Baby Daddy" is a hilarious new original comedy about a young man who becomes a surprise dad to a baby girl when she's left on his doorstep by an ex-girlfriend. "Baby Daddy" makes its world premiere on WEDNESDAY, JUNE 20 (8:30 p.m., ET/PT), following an all-new "Melissa & Joey" on ABC Family.

"Baby Daddy" follows Ben (Bilodeau), a young man in his early 20's living the life of a bachelor as a bartender in New York City with his buddy Tucker (Mowry) and his brother, a professional hockey player, Danny (Theler). Their lives turn upside down when they come home one day to find a baby girl left on his doorstep by an ex-girlfriend. After much deliberation, Ben decides to raise the baby with the help of his friends and his protective -- and sometimes over-bearing --mother Bonnie (Peterman) and his close female friend, Riley (Kane). Riley, who has had a secret crush on Ben since childhood, was once the overweight girl next door they'd nicknamed "Fatpants," but has now blossomed into a beautiful young woman attending law school. Riley is hopeful that Ben will finally take notice, but she doesn't realize that Ben's brother, Danny, is harboring a secret crush on her.

The series stars Jean-Luc Bilodeau ("Kyle XY"), Derek Theler ("90210") and Tahj Mowry ("The Game"), along with Melissa Peterman ("Reba") and Chelsea Kane ("Dancing with the Stars," "Jonas LA"). "Baby Daddy" is created and executive produced by Dan Berendsen ("The Nine Lives of Chloe King," "Sabrina, the Teenage Witch" and "Hannah Montana: The Movie"). "Baby Daddy" is a multi-camera comedy that shoots in front of a live studio audience in Los Angeles.
