Media and fans have been asking whether former Beatle Sir Paul McCartney is now vegan.
The musician - who famously said, 'if slaughterhouses had glass walls, everyone would be a vegetarian', hasn't eaten meat for many years.
His first wife - the late Linda McCartney was also a vegetarian advocate, and set up her own range of veggie foods.
But now many are questioning whether the superstar has taken the next step and moved to an entirely plant-based diet.
The speculation is based on a tweet from a woman whose parents attended one of the rocker's concerts in Illinois.
According to the Twitter user - who calls herself plantifulemily - her parents sent her a photo of the menu at the concert, which only featured vegan dishes including buffalo cauliflower and plant-based chilli fries.
She tweeted: "My parents are at the Paul McCartney concert and he demanded that there only be vegan food, king!"
According to the music press, McCartney has made similar demands in the past - telling organizers in Canada in 2013 that he wouldn't perform unless they could promise no meat would be consumed backstage.
He allegedly made a similar request in 2002 - requesting no furniture in his dressing room was to be 'made of animals'.
