It looks like Bobby Flay and Brooke Williamson‘s offscreen chemistry is heating up.

The Bobby’s Triple Threat costars fueled dating rumors April 6 when they enjoyed a night out to catch the New York Knicks take on the Phoenix Suns at Madison Square Garden. Alongside a photo of Brooke sitting courtside at the basketball game, Bobby wrote on Instagram Stories, “Food, service and slams were all first rate!”

Thanking the home team, the longtime Food Network host added April 7, “A great game and a great win last night!”

The outing comes three weeks after Bobby sparked romance rumors with the Top Chef winner, when they attended a No Kid Hungry charity dinner together in Los Angeles.

Bobby’s 28-year-old daughter Sophie Flay—who the celebrity chef shares with ex-wife Kate Connelly—further fueled relationship speculation earlier this month when she revealed that her dad “always has a date” to Hollywood events.

In addition to his three-year marriage with Kate during the late ’90s, Bobby was previously wed to chef Debra Ponzek from 1991 to 1993 and to Law & Order: Special Victims Unit actress Stephanie Marsh from 2005 to 2015.
