According to MTV, Bookout found out that she was pregnant with baby number three right after she got engaged to McKinney.

"I found out I was pregnant with baby number three right after we got engaged," she explained to the network. "It was not expected or a planned pregnancy."

The once again mom-to-be is due on May 30. That's around the same time her daughter, Jayde Carter (May 29, 2015) was born last year. Having two children under one-years-old will make her daughter, and son, "Irish twins." As for comparing her third pregnancy,

"Because it's the third one, you know what's going on. You've been there, done that a couple times now, so it's sort of laid back," she said.

She revealed that she was craving pineapples this time around. Bookout's husband-to-be wasn't upset to learn that he'd be a father again. He was actually overly excited.

"I was definitely more excited," McKinney said. "She had a bit of a breakdown."

"Yeah, because y'all don't have a clue," Bookout replied.

As for Bentley Edwards, (Maci and Ryan Edwards son) Bookout said that her son was super happy to be having a little brother.
