Usher found being a vegan too expensive.

The 'Good Kisser' hitmaker has confessed he ditched the diet - on which you cannot eat meat or any other animal products - because he was spending too much money on maintaining it.

Referring to the private chef he had travel with him on tour, he said: ''That was opulent as hell.

''It was just difficult to find people who can make vegan food taste great.''

However, the 36-year-old star - who has sons Naviyd Ely Raymond and Usher Raymond V from his marriage to ex-wife Tameka Foster - is now following an even stranger food regime.

He explained to Billboard magazine: ''These days, I try to eat for my blood type when I'm not eating for the fat kid inside me.''

Quizzed on what he meant by eating for his blood type, he added: ''A doctor I know came up with it, but hasn't released it yet, so I don't want to tell you too much about it.

''But the idea is to eat the foods that work best for your body. For my blood type the meats I can eat are pork, beef and fish.''
