PETA has a bone to pick with Big Boi. Following his performance with Maroon 5 at the Super Bowl Halftime Show on Sunday (Feb. 3), PETA sent a letter addressing Big Boi by his first name, Antwan, and called out the OutKast rapper for his decision to wear a fur coat during his set.

TMZ got ahold of the of the note and posted it on their website. “Our hearts sank when you took the stage during the Super Bowl in a fur coat,” the letter reads. “You have many, many fans here at PETA and around the country who love your music, and were thrilled when it was announced that you’d be involved in the halftime show. Can we please convince you to make that your last appearance in a fur coat?”

PETA goes on to offer the “Kryptonite” rapper an opportunity to make amends — by donating all of his fur coats to the homeless. “We’ve given furs to homeless shelters in this country and sent donated furs to Syrian refugees who desperately need the extra warmth. We’d be honored to add any furs to this donation program.”

In exchange for the donation, PETA says it will send Big Boi a “beautiful” faux fur coat that “offers a look that kills that no animal had to die for.” According to TMZ, PETA believes the coat Big Boi wore during his performance at the Super Bowl was made of fox fur. The animal rights group estimate the coat cost up to “25 red foxes their lives” via electrocution.

No word on if Big Boi will donate his Super Bowl fur to PETA. The rapper has yet to issue a statement confirming if he was wearing genuine fur. However, stars like Mariah Carey and Sharon Osbourne have donated their furs to PETA’s program in the past, Billboard reports.
