Pink enjoys getting ''really fat'' when she isn't working.

The 'So What' hitmaker needs to consume a lot of food to cope with her gruelling physical shows and preparations when on tour, but admits she doesn't change her diet once the concerts are over.

She said: ''I eat a lot [on tour], because I work out four and a half hours a day: a two-hour show, plus yoga, cardio and a rig check with the flying apparatuses. But here's the issue; I don't change my eating when I get home. So everyone always asks me, 'What are you going to do after?' And I say, 'Get really fat and happy.' ''

The 36-year-old singer - who has four-year-old daughter Willow with husband Carey Hart - is passionate about food and loves attending cooking classes when she has free time.

She told Food and Wine magazine: ''I take cooking classes for vacation. Last summer I went to Les Prés d'Eugénie, Michel Guérard's place in France, for five days. We made croissants and coq au vin. They have an incredible wine list.''

And Pink is currently ''obsessed'' with using halloumi in her dishes.

She said: ''I'm obsessed with halloumi. I grill it for salads with truffle oil and dandelion greens--the more exotic the greens, the better. I don't care if people think halloumi's squeaky; they're wrong.''

The 'Try' singer's young daughter shares her love of food and recently ''went through a clam phase''.

Pink explained: ''She loved them because the shells are like Pac-Man!''
