No baby daddy drama here.
"For the record, the only thing this handsome guy has in common with any chef," the Bravolebrity tweeted May 8 in response to the speculation, "is the tendency to get emotional around meal times."
Kate's response comes after some fans questioned if her former co-star and one-time love interest Chef Ben Robinson is Sullivan's biological dad. "He's a good looking guy and does have sort of a Ben look? No?" one user wrote on Twitter while another shared, "He's the best thing Ben has cooked all year. Just kidding, congratulations Kate, he's absolutely perfect."
The former chief stew and chef—who co-starred on the Bravo series for three seasons before he left after season four—first sparked romance rumors between seasons two and three. Kate later confirmed they once hooked up off the show during a July 2019 Watch What Happens Live interview. Though their fling was short-lived, they have since remained good friends.
Last month, Ben proved they were still close by posting a sweet photo with a nine-month-pregnant Kate.
"Who knew that Kate Chastain and I would be the same weight one day," he wrote in an April 10 Instagram post. "But to be fair I have been hitting the gym! Please wish my great friend @kate_chastain an easy delivery and a healthy beautiful baby! I am so proud of who you have become and the mother you will soon be.
The Traitors alum announced Sullivan's arrival on May 5, writing on Instagram, "Hard Launch: Sullivan Cay," along with the first photo of her little one in the delivery room.
