Teen Mom 3's Brittany DeJesus Stunned to Learn Her Dad Is Not Her Biological Father: 'I'm Going to Throw the F--k Up'

The truth finally comes out! In Family Therapy With Dr. Jenn's stunning Wednesday, April 20, episode, Teen Mom 3's Brittany DeJesus learns that her dad is not her biological father, as seen in Us Weekly's exclusive sneak peek.

The VH1 series' preview clip shows Brittany taking part in a therapy session with her mom Roxanne, her sister Briana and Dr. Jenn Mann.

In the scene, Brittany — who appeared on MTV's Teen Mom 3 in 2013 to support her sister, Briana, who is mom of daughter Nova — asks her mother to tell her the truth about her dad, to which Roxanne replies, "Daddy's not your daddy."

Brittany is stunned and says, "I'm going to throw up all over you in like 2.5 seconds, seriously.… I feel like I'm going to throw the f--k up."

After Brittany storms out of the room, Roxanne tells Briana about their father, "He's your daddy, but not hers." When the 16 & Pregnant alum asks where Brittany's biological father is, Roxanne responds, "He's dead."

Watch the chaos unfold in the video above.

Family Therapy With Dr. Jenn airs on VH1 Wednesdays at 8 p.m. ET.
