Ashlee Simpson Cares for Injured Pete Wentz

"When I'm being hard-headed and I don't want to elevate it, she says, 'No, put it on the pillow!" he told PEOPLE at his bar, Angels and Kings, in New York's East Village. "When I try to get in the shower by myself and am going to end up falling on the hotel room floor, she's good at stopping me."
And while Wentz, 28, judged the "Vive le Karaoke" contest, sponsored by Hilfiger Denim and Nylon Magazine, he lamented his choice in foot braces – a black "rocker boot."
"I jumped off a ten-foot stack [of speakers] ... and I broke my foot," the Fall Out Boy bassist explained. Doctors told him he could either wear a "rocker boot" for six weeks or a "hard cast for three weeks."
"The rocker boot sounded really enticing," Wentz admitted, "But I didn't realize that it does not rock at all."
During the competition, Wentz gave celebrity photographer Jamie McCarthy high marks for his karaoke – 8 out of 10 for his "rock moves" and for "not using the photos where I look like I have a fat face."
He also mentioned that in Japan, where he first "embraced karaoke," he performed Metallica and Bon Jovi. "People go into it with no ego there. When somebody comes in and is really good, it is kind of a bummer. If you're crummy, just go for it," said Wentz. Simpson – by his side all night – chimed in that, if she were to take the stage, she would perform "Janis Joplin."
