The 52-year-old actress said on Monday's episode of Jimmy Kimmel Live! that her pandemic circle consists of Cox, Jimmy Kimmel Live! host Jimmy Kimmel, her Horrible Bosses co-star Jason Bateman and their families.
Aniston she's mainly stayed home during the pandemic, with the exception of work and her small group of friends.
"I've been in the house a lot," Aniston said. "I've rearranged furniture ... I went from the set from Sony studios to shoot [The] Morning Show right back to my house."
"It was like a star, the points that I would go to -- I'd go to work, I'd go to Courteney's. I've been to you guys, to the Batemans, and then that was back home," she added. "So it was kind of like we had this little bubble of friends -- thank god I love all of you so much."
Aniston and Kimmel recalled how Aniston recently lost her ring in a salad during an evening at Kimmel's house. Kimmel had recently turned Aniston on to the Oura Smart Ring, a ring that tracks sleep.
"I'm addicted to it," Aniston said. "I was talking about how this is ruining my life because I'm so obsessed with the Oura ring and looking at my sleep patterns and how badly I sleep and it shames me every day, and then all of sudden I look up but it's gone. I'm just like, 'Oh, god, Jimmy.'"
Aniston said she dug through the salad but couldn't find the ring.
"I go, 'Well, somebody's gonna find it... eventually,'" she said.
Aniston and Kimmel then found her ring next to the salad.
Aniston is best known for playing Rachel Green on Friends. She portrays Alex Levy on The Morning Show, which will return for a second season Friday on Apple TV+.
