Bobby Flay and Girlfriend Brooke Williamson Take BottleRock Festival Stage with Ken Griffey Jr. and Kate Hudson

Bobby Flay and Brooke Williamson shined at BottleRock Napa Valley!

On Memorial Day weekend, the chefs-turned-couple were spotted together, and they also separately took the stage with Ken Griffey Jr. and Kate Hudson for culinary demonstrations during the music festival in Napa, Calif.

The Beat Bobby Flay star, 60, and Griffey Jr., 55, demoed on Sunday, May 25, while the Sun-Kissed Cooking cookbook author, 46, and Hudson, also 46, shared the stage on Saturday, May 24.

Williamson shared an Instagram Stories selfie with Hudson, who had her arms wrapped around the celebrity chef’s shoulders.

Flay and Williamson went public with their relationship in March.

“They have been friends for a while and recently decided to jump in,” a source told PEOPLE at the time. “Her divorce last year probably gave them some additional shared experiences and over the last few weeks, love bloomed.”

The two chefs work together on Bobby’s Triple Threat, and Williamson has competed on Beat Bobby Flay. The pair is next set to appear together on Food Network’s BBQ Brawl, which premieres June 1. 

On Thursday, May 22, Flay revealed that the foodies will be sharing the stage for a non-culinary competition on his Instagram Stories. 

He shared a photo of himself, Williamson, daughter Sophie Flay, chef Ayesha Nurdjaja and chef Michael Voltaggio taking a selfie and wrote, “Can’t wait for you all to catch this episode of Celebrity Family Feud … stay tuned for info about the air date.”
