Celebs are no strangers to controversy. In the past few聽weeks alone,聽Demi Lovato took some serious heat for her hairstyle聽in her new 鈥淣o Promises鈥 video after some viewed it as cultural appropriation, and聽Miss USA聽was slammed for her comments regarding feminism and health care. Now, Jamie Foxx is getting his own dose of backlash for 鈥 get this 鈥 making up sign language聽on TV.

It was during his Friday night appearance on聽The Tonight Show Starring Jimmy Fallon聽that Foxx, for whatever reason, thought it would be funny to mimic sign language as the host聽threw the segment to a commercial break.

His questionable 鈥渏oke鈥 instantly offended fans, 28-year-old model and聽Dancing With the Stars聽season 22 winner聽Nyle DiMarco (who just so happens to be deaf), included. The reality show alum slammed Foxx on Twitter, sharing a video of the incident and calling it 鈥渟traight up disrespectful.鈥

DiMarco went on to post聽an open letter聽aimed at the 49-year-old actor, writing: 鈥淛amie Foxx鈥檚 behavior with Jimmy Fallon on Fallon Tonight should not be tolerated anywhere.聽We simply do not make fun at the expense of other cultures especially those with a history of being marginalized. When we do this, progress takes a step backward.鈥

The passionate advocate then sent out one last tweet, this time addressing Fallon and his show, asking: 鈥@jimmyfallon@FallonTonight how was this allowed? How was this allowed? Where鈥檚 the cultural sensitivity. Not comedy when you make fun of others.鈥

DiMarco聽wasn鈥檛 the only high-profile name to scold the Oscar winner.聽Marlee Matlin, a fellow DWTS contestant, activist, and actress, also took to Twitter to address the incident聽as soon as it happened. Choosing to use a somewhat lighter tone, she wrote:聽鈥淢r. @iamjamiefoxx. I鈥檇 be happy to give you sign language lessons so you could be funnier.鈥

Non-celebs also made sure to voice their opinions, calling Foxx鈥檚 actions聽鈥渞ude鈥 and 鈥渙ffensive.鈥

Foxx has yet to respond.
