Kanye West Sporting Bump on Forehead After Run-in With Street Sign

Rapper suffered the bruise when he and Kim Kardashian were surrounded by paparazzi Friday

Ouch.

After running into a street sign and going totally ballistic on the paparazzi surrounding him and girlfriend Kim Kardashian, Kanye West emerged today in Beverly Hills with a bruise on his forehead.

The bang-up went down Friday when he and the seven-months-pregnant reality star were heading to 9021Pho in Beverly Hills for lunch and got swarmed by the paps.

While trying to ignore the shutterbugs, Kanye ironically walked straight into a metal "Wrong Way" street sign.

Kim tried to lessen the blow by placing a kiss on his forehead, but Kanye was livid nonetheless, exploding on nearby paparazzi—who still continued to snap his photo post-bump.

A source told us Kanye's mood lightened when the couple left the restaurant, though, with the rapper nodding to a pap to show that everything was cool.
