Fall Out Boy's Wentz sues over song

Fall Out Boy's bassist Pete Wentz has launched a legal battle against Canadian band Neurosonic for exploiting his girlfriend Ashlee Simpson, according to reports.

The group's song 'So Many People' references American TV show Saturday Night Live, on which Simpson was famously slammed for lip-syncing during her performance.

Neurosonic sing in the track: "Everything under the sun / Going to hell in an episode of SNL / Busted on the TV / You ugly girl, you cannot sing / Can't even lip sync / Apparently money can even buy you dignity".

Frontman Jason Darr also reportedly encouraged the audience at the Knitting Factory in New York to mimic a dance similar to Ashlee Simpson after her performance on show.
