Ferrier is due to give birth in late October and is keeping the sex a secret for now. She said she and her boyfriend have picked a name for their unborn child.

"Yeah, that was one of the first things," the star said. "I think we went back-and-forth a little bit, but I got my way in the end."

Ferrier has starred in all five seasons of "Below Deck Mediterranean."

Season 5, co-starring Sandy Yawn, Malia White, Lara Flumiani, Pete Hunziker, Hindrigo "Kiko" Lorran, Jessica More, Alex Radcliffe and Robert Westergaard, premiered on Bravo last week.
