Vegan Sir Paul McCartney is furious a meat-selling fast food chain have used his photograph in its restaurants.
The former Beatle - a long-time vegetarian campaigner - was stunned to learn MCDonald's were using his image in his hometown branch of Liverpool.
MCCartney's spokesman Geoff Baker says, "What sort of morons do MCDonald's think Beatles fans are?
"It's ridiculous and insulting to use images to peddle hamburgers. Fans should boycott MCDonald's - and not just in Liverpool."
MCCartney is also ambassador for People for the Ethical Treatment of Animals.
A PETA spokeswoman says, "He became a vegetarian after watching lambs play in a field outside his home and surely would not want anyone to use his likeness to help promote meat.
"We hope anyone who sees his picture on the wall will be reminded that he's a vegetarian and skip the Big MAC for a veggie burger."
A MCDonald's spokeswoman says the pictures were to "acknowledge the outstanding contribution the Beatles made to both local and global culture".
