CHATTANOOGA, Tenn., Dec. 29 (UPI) -- Maci Bookout is pregnant with her second child.
The 23-year-old reality star announced the news in an interview with In Touch Weekly. Bookout is already mother to 6-year-old son, Bentley, with ex-fiancé Ryan Edwards, and is expecting her first child with boyfriend Taylor McKinney.
"I didn't think that another pregnancy was possible," the star, who is diagnosed with polycystic ovary syndrome, told the magazine. "We still can't believe it. It was a huge shock, but we are very excited ... This baby is such a blessing. I'm calling her my miracle baby."
Bookout came to fame on season one of MTV reality series 16 and Pregnant. She went on to appear on four seasons of spinoff show Teen Mom, and will return for a fifth season with original stars Catelynn Lowell and Amber Portwood in 2015.
Lowell is currently pregnant with her second child by fiancé Tyler Baltierra. The couple are also parents to 5-year-old daughter Carly, whom they gave up for adoption in 2009. Portwood is mother to 6-year-old daughter Leah with ex-fiancé Gary Shirley.
