Jesse McCartney at RedZone Entertainment and Radio Killa Records 2009 Pre-Grammy party held at STK. Los Angeles, California - 06.02.09

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."
