Rocker Pete Wentz proved he has a strong stomach when he downed a glass of snake's blood during a trip to Taiwan.

The Fall Out Boy star and his bandmates visited the capital Taipei's famous Snake Alley market, where he drank a vile concoction of reptile blood mixed with wine.

He tells Q magazine, "(It was) in a place called Snake Alley. They show you the snake alive, and then you start with wine, then you drink the venom, you drink the sperm, and end it with some kind of ginseng energy thing. It's meant to make you invigorated, and we were f**king pumped."
