Animal activists at PETA have lashed out at pop star Jesse McCartney after he confessed to eating monkey brains on a recent trip to Asia.

The singer/songwriter wasn't fond of the idea of tasting the local delicacy but admits it wasn't a bad meal.

He says, "It was a little chewy and a little bland. It could have been seasoned a little bit more to tell you the truth."

But PETA chiefs are far from impressed with the star's adventurous appetite and insist the singer should consider becoming a vegetarian.

Spokesman Michael McGraw says, "You'd have to be bananas to eat monkey flesh, or any meat. When it comes to the ability to feel pain and suffer, a monkey is no different from chickens, cows and pigs. All animals deserve respect, which is why PETA promotes a vegetarian diet."
