Although Bookout is currently expecting her second child, the Teen Mom OG star hasn't slowed down when it comes to her education and career. In addition to preparing to graduate, the young mother is working a social media marketing specialist and doing a great job with her son Bentley, who recently started going to school full-time.

In a new interview, Bookout opened up on returning to MTV.

"It had been a very long time since we had been on the show," Bookout told PEOPLE Magazine earlier this month. "I wasn't getting recognized everywhere I went anymore and people didn't really care. It was very quiet."

"I was definitely apprehensive," she continued. "But I thought it was really cool and all of us are in such different places in our lives that it would be nice for the fans to see how much we have grown."
