Who is her baby daddy? In an In Touch exclusive sneak peek video for today’s episode of Teen Mom: Young and Pregnant, Brianna Jaramillo learns who the father of her son, Braeson, is. And it looks like it’s someone she doesn’t expect.

In the clip, Brianna, 19, gets the results of a paternity test and looks at them on a computer. Her mom, Jessica, asks if she can look at it as Bri explains that the paternity is almost a 100 percent match. “You were so sure it wasn’t him,” the young mom’s mother says. “I know,” Brianna responds, although the video holds off on revealing who the results concluded Braeson’s father is.

“I don’t know how I feel,” the reality star explains. “I’m not happy and I’m not sad. You know what I mean? … I feel like I’m just in shock.” “It’s probably gonna be a bit of a shock to him too,” Brianna’s mom says.

“What’s gonna happen from here?” Bri questions. She later adds, “I just feel like everything is gonna change. Like, my future that I was expecting with Braeson … it might not just be me anymore. You know? Like, everything that I have, like, imagined as our future has to include this guy now.”

Brianna Learns Who Her Son's Baby Daddy Is in 'Young and Pregnant' Clip- 'I Don't Know How I Feel'

The reality TV personality’s mother reminds her that she chose to have sex and got pregnant, and Bri interjects, “I know. I just wish I could have had sex by myself and had a baby by myself. He was just all mine. It was so much better when he was just mine.”

Brianna adds before the end of the clip, “It’s just a lot to take on. And I don’t know how I feel. And it’s just a lot of emotions right now.” As she gets emotional, her mom offers her a hug, which she accepts.

Previously, viewers witnessed the relationship between Bri and her boyfriend, Danae, rather than between Brianna and the biological father of her son. But her season 2 MTV cast bio reads, “After leaving her toxic relationship with Danae behind, Brianna moved with her mom and Braeson to Oregon for a fresh start, but it was tougher than she expected to juggle two jobs and raise Braeson on her own. Brianna started dating again when an old friend reached out with some surprising news that could change the course of her and Braeson’s life forever.” So it sounds like new revelations will be a big part of Bri’s overall journey this season.

Teen Mom: Young + Pregnant airs on MTV Tuesdays at 9 p.m. ET.
