Pete Wentz denies issuing a cease-and-desist order

Pete Wentz denies issuing a cease-and-desist order against a Canadian band over a song that pokes fun at his girlfriend, Ashlee Simpson, PEOPLE reports

During a recent Neurosonic concert at NYC's Knitting Factory, the band's Jason Darr introduced the song "So Many People" by saying Wentz had sent the band a letter regarding the tune.

The New York Post's Page Six reported that Wentz had taken legal action, but a rep for the Fall Out Boy bassist, 28, tells PEOPLE that is not true.

"I've never heard of [the song]. Pete's never heard of it. No one's ever heard of it," says the rep, Bob McLynn. "Pete's not the kind of guy who would do a cease or desist with anything. He believes in artistic freedom."
