Pete Wentz loses bet, gets friend's face tattooed on his leg

Cobra Starship singer Gabe Saporta is signed to Pete's record label overseas, and has been involved in a prank war with him for a while now - with Pete wearing Gabe's phone number on a t-shirt to the recent MTV Video Music Awards.

Gabe responded by revealing Pete's email address at the Spanish MTV Awards... but the worst was obviously yet to come.

“Well, I promised Gabe if [his band's song] ‘Good Girls Go Bad’ went platinum, I would let him pick a tattoo to put on me,” Pete said.

“A man with such humble beginnings, of course, chose a self-portrait.”

Not just a self-portrait - the tatt also features the inscription “Gabey Baby Made Me Go Bad.”

“I held through with the bet,” Pete said. “But let’s see if Gabe holds through with his end of the bet if [Gabe's band's album] goes gold.”
