"Happy birthday to the absolute loveliest and most genuine person in my life. Love you CP. @christinalperez," Flay, 59, wrote in the caption accompanying the snapshots, which led off with a sunkissed selfie of the two.

Pérez, a vegetarian, has had an impact on Flay's methods in the kitchen. "She's teaching me to cook with a lot less meat," he revealed at the time.

"Christina has spectacular style and she's just one of these people that just gets it. She understands style and class and if something doesn't seem right to her, she'll tell me," he said.
