TV CHEF ALEX’S LOVE IS TOAST

THE romance between

Food Network star Alex Guarnaschelli, 49, and chef Michael Castellon, 40, has gone stale — the foodies have called off their engagement after five years together!

Chopped judge and former Iron Chef competitor Alex was previously married to Brandon Clark, with whom she shares 12-year-old daughter Ava.

Michael, who first caught Alex’s eye when he cooked her a spectacular steak, has said of the split: “Wishing her nothing but the best.”
