The few remaining teams in the World Cup may not want Mick Jagger in their corner.

It seems the Rolling Stone frontman has developed a reputation for jinxing whatever team he supports. Some Brazilian fans are even blaming Jagger for their team's 7-1 thrashing by Germany in Tuesday's semifinal game.

The 70-year-old singer turned up at the game with his 15-year-old son by Luciana Giminez, a Brazilian model and celebrity. Though he wore an England cap, his son was clad in Brazil jersey and they were surrounded by Brazil supporters.

The legend of the "Jagger Curse" dates back to the 2010 World Cup in South Africa, where he sat next to Bill Clinton for the USA-Ghana match, only to see the U.S. lose 2-1. When he attended the England-Germany game the next day, wearing an England scarf, his home country lost. But it wasn't until the Dutch defeated Brazil during the quarterfinal round, where Jagger turned up in a Brazil shirt, that the Brazilians first blamed him for the loss.

When this year's World Cup kicked off in Brazil, Jagger was on tour with his band, but his influence was still felt. After he touted Portugal as his tournament favorite, followed by England, neither made it past the group stage. He also predicted that England and Italy would beat Uruguay. Instead, Uruguay won both games - and England and Italy went home early.

When Brazil made it to the semifinal, locals begged "Pé Frio" or "cold foot," as Jagger was dubbed, not to attend or even offer any encouraging words. But just in case, some fans came prepared with a cardboard cutouts of Jagger wearing a Germany jersey.

No word from Jagger's rep on who he's supporting in today's semifinal between Argentina and Holland.
