When MTV darlings Fall Out Boy failed to secure a single Grammy nomination last week, the boys in the band decided to play the blame game. And OK! has learned that this time the blame may lie solely on the shoulders of bassist Pete Wentz’s gal pal Ashlee Simpson.

“Grammy voters are fed up with Ashlee after she was caught lip-synching,” says a pal of the band, referring to the younger Simpson sister's hilariously embarrassing October 2004 appearance on Saturday Night Live, when she was caught pretending to sing along to her own tune. “And her relationship with Pete has definitely affected public opinion of the band."

So could Ashlee be the 21st century answer to Yoko Ono and cause the band to split? "The guys in Fall Out Boy are furious," explains the source. "They think everything Ashlee touches is poison, and they really want her to stop touching Pete!”
