Jennifer Aniston wants people to “wear a damn mask” after coronavirus nearly took the life of one of her own friends.

On Sunday, the “Friends” star shared a photo of her pal Kevin, who was hospitalized with COVID-19 in April, and had to be intubated. She said he was “perfectly healthy, not one underlying health issue.”

“This is Covid. This is real,” Aniston, 51, added, also sharing another photo of her and her former co-star, Courteney Cox, wearing matching face masks. “We can’t be so naive to think we can outrun this…if we want this to end, and we do, right? The one step we can take is PLEASE #wearadamnmask.”

The actress asked her fans to “think about those who’ve already suffered through this horrible virus,” and to use protection for their families and themselves because COVID-19 “affects all ages.”

Aniston concluded her statement by sharing that Kevin has thankfully “almost recovered.”

The Hollywood star’s famous pals, including Gwyneth Paltrow and Michelle Pfeiffer, cheered her on for raising awareness.

“Right on sister,” Paltrow, 47, commented. Pfeiffer, 62, added, “Baffling why this so hard for some people.”

Cox, 56, also encouraged her followers to use face masks on her Instagram with a playful video of her dogs.

Aniston and Cox are among a large group of celebrities that have used their social media platform to advocate for the use of masks.

In June, Aniston said on Instagram she understood masks can be “inconvenient” and “uncomfortable,” but pointed out that “so many lives have been taken by this virus because we aren’t doing enough.”

“This simple and effective recommendation is being politicized at the expense of peoples’ lives,” she said. “And it really shouldn’t be a debate.”
