Maci Bookout & Taylor McKinney Are 'Parents In Training'

After revealing her baby news earlier this week, the Teen Mom star is getting ready for her daughter's birth later this year by deciding on a couple of baby names -- June and Harley. However, when it comes to Harley, Bookout has one major issue.

"We have Bentley, so it’s kind of too many automobiles going on,” Bookout explained, according to an OK! Magazine report on Wednesday.

Will Farrah Abraham Be Featured On 'Teen Mom' Season 5?

Bookout welcomed her first child, son Bentley, now 6, with ex-boyfriend Ryan Edwards during the filming of MTV's 16 & Pregnant season 1. Years later, after Teen Mom was placed on hiatus, Bookout began dating McKinney.

“Last time, there was a lot of worry and concern,” she explained. “It was just me and Bentley facing the world together, and I had to figure things out as I went. This time, I’m able to be excited because I’m older and able to give my baby the stability of the relationship that Taylor and I have.”

Bookout and McKinney have been dating for years, and will likely be seen together when Teen Mom returns to MTV for season 5 later this year.

As Us Weekly reported over the summer, Bookout, along with Catelynn Lowell and Amber Portwood, will be sharing more of her story with fans in the upcoming season. Former cast member Farrah Abraham will not be a part of the new season.
