Below Deck Hall of Famer and alumna Chief Stewardess Kate Chastain shot down rumors her newborn baby son’s father is co-star Chef Ben Robinson on Monday. Chastain announced to the world she gave birth to a newborn son, Sullivan Cay, on May 5, 2023. Since the queen Below Deck chief stew announced she was several months pregnant back in the middle of December 2022, fans speculated Robinson was the baby’s daddy. Kate and Ben, now Galley Talk co-stars after hanging up their epaulettes on Below Deck, even fueled the rumors with some of their on-screen banter while commentating on the latest season of Bravo’s hit yachting show.
Once Chastain posted her first picture of her son to Instagram fans again started believing it was Ben because they could apparently see a resemblance.

Well, after giving birth to her newborn, Kate’s finally putting the rumors to bed. “For the record, the only thing this handsome guy has in common with any chef is the tendency to get emotional around meal times.”

Below Deck fans will have to wait and see if Chastain eventually spills the tea on who the dad is. Some are speculating she used a sperm donor as she hasn’t been in a public relationship for some time. Fans may recall Kate’s previous long-term relationship with a same-sex partner ended up with her arrested for assault (the charges were ultimately dropped).
