The VH1 star recently made headlines after employees at his Flavor Flav's Chicken restaurant, in Iowa, claimed their paycheques had bounced.
Now the animal rights organisation has reportedly sent the hip-hop artist an open letter urging him to turn his restaurant into a vegetarian establishment.
According to BET.com, the letter says: 'Greetings from PETA! After reading about the debacle involving employees of your fried-chicken restaurant in Clinton, Iowa, whose paycheques bounced, we're writing to encourage you to bounce one more thing – cruelty – and make your restaurant vegetarian.'
