Sarah Michelle Gellar is so keen to ensure husband Freddie Prinze Jr. eats healthily, she's started implementing spot checks on his dietary habits.

Freddie, lunching with his agent at a swanky Beverly Hills restaurant, had just ordered a juicy T-bone steak when his phone rang, reports Teen Hollywood.

Sources claim that it was Sarah checking on his choice of lunch, then telling him off for not eating healthily enough. After the call, Freddie prompty changed his order to a salad.
