Maci Bookout can tick off one very important item on the baby planning list: deciding on a name for her little girl on the way. What's the winning moniker? A quick hint: It isn't June or Harley like the "Teen Mom OG" cast member indicated when she first announced she was expecting a few months back.

"It's Jayde and her middle name is Carter," the 23-year-old, who will document her pregnancy with longtime beau Taylor McKinney on this season of "TMOG," confirmed to E! News. Like Juliet memorably declared during Shakespeare's masterpiece -- what's in a name?

Apparently, a whole lot. Bentley's mama revealed that Jayde was going to be the peanut's middle moniker, but she and Taylor were struggling to come up with a first name. "Nothing was sticking, so finally I was like, 'We keep going back to Jayde -- why don't we just name her Jayde?'" she said.

Even though M and T really liked June -- they scratched it because the bundle of joy is due that month -- they used June Carter Cash as inspiration for their kiddo's middle name.

"That's like the first name that we were both like, 'That's it.' No more changes," the Tennessean added. "We finally agree and really feel like this is the perfect fit."
