Jamie Lynn Spears Found Out She Was Pregnant In A Gas Station Bathroom

"My world came crashing down."

Jamie Lynn Spears found out she was pregnant the way many women do. 

"I don't know how you can say this without feeling a little tacky. I kept actually throwing up," she revealed on the new episode of her TLC series, "When The Lights Go Out." She was 16 years old at the time and the star of Nickelodeon's "Zoey 101." "We didn’t want to do it at home, so I went in the BP [gas station] and I took a pregnancy test," she said, according to Us Weekly. "I sat on the thing, and we were sat there looking and my friend looks down and she freaks out and I was like, 'What? What? What?'" 

A teary-eyed Spears said her "world came crashing down" when she found out she was pregnant. Her parents were both in disbelief and she felt guilty. Things were "not great" for a while, but the teen star was determined to raise her child. 

"I knew I had a lot of young girls who looked up to me and I felt that responsibility, but at the end of the day I knew I would have to make a decision as a young girl myself, to do something that I could sleep with at night," she said. "I knew deep down that I was going to have my little girl, even if I had to raise her on my own, which is what I did." 

"When The Lights Go Out" airs Sunday at 10 p.m. on TLC.
