The Teen Mom OG star revealed in an interview with MTV News that she plans on naming her unborn son, who's due at the end of May, Maverick Reed.
Bookout, who is mom to son Bentley, 7, with ex Ryan Edward, also shares daughter Jayde, 11 months, with her fiancé Taylor McKinney.
According to the MTV star, the happy couple decided on the name together.
"Maverick was actually one of our boy name choices when we were pregnant with Jayde before we knew it was a girl," Bookout, 24, said. "Reed is a family name for both our families. We were also considering Connor for the first name, but we decided Maverick went better with the names Bentley and Jayde."
Bookout and McKinney got engaged in January and announced they were expecting in February.
