Her Mom co-star Allison Janney addressed how Anna’s dealing with the breakup.
"She just is a trooper. She comes to work with a smile on her face," Allison told E! News. "She's a professional. I love her to death."
In fact, Allison had nothing but praise for her co-star.
"Her private life she keeps pretty much to herself. She comes to work and gets the job done. She's great," Anna's on-screen mum gushed.
The two are currently filming the fifth season of their show, with Allison revealing that the cast and crew are all helping Anna through this difficult time.
“We're all very supportive of her and love her and feel badly for both of them. We love them both,” she said. “They're such great people.”
Chris and Anna shocked fans on August 6 when they called it quits on their eight-year marriage.
"We tried hard for a long time, and we're really disappointed," the couple – who share a son Jack, four – wrote in a joint statement.
“Our son has two parents who love him very much and for his sake we want to keep this situation as private as possible moving forward. We still love each other and will always cherish our time together and continue to have the deepest respect for one another,” they said.
Anna has also thanked her fans for their support in an August 15 episode of her podcast, Anna Faris Is Unqualified. "I just want to thank you all so much for all the love I've been receiving and I truly love you," she said.
