Allison Janney Talks Anna Faris Leaving 'Mom,' Says 'It's a Huge Loss'

Allison Janney is opening up about Anna Faris leaving Mom.

Ahead of the season eight premiere later this week, the 60-year-old actress who plays Bonnie to Anna‘s Christy on the show, said that her co-star leaving the show was “a huge loss.”

“It’s a huge loss for the show to not have Anna because she was part of creating a character, Christy, that everyone fell in love with, who was so lovable and warm and gullible and funny and we will miss her so much,” Allison told Entertainment Tonight.

“I think I’ll miss the most, for me, the relationship between Bonnie and Christy, even though that will still continue,” Allison continued. “But she won’t be present. That’s what I’ll miss.”

Anna shocked fans back in September when she announced that she was leaving Mom after seven seasons.

“The past seven years on Mom have been some of the most fulfilling and rewarding of my career,” she said in a statement at the time.

Jaime Pressley, who plays Jill Kendall on the show, also talked about Anna‘s absence in the new season.

“I do want to say that it feels like she’s still here because we do talk about the character all the time,” Jaime said. “And [Janney's] character is always calling her or vice versa. We still hear the name, we still talk about her. She’s not gone as far as we’re concerned, and we all spent so much time together over the years and love each other and support each other and we all want each other to be happy, so we’re happy for her and we miss her no matter what.”

Season eight of Mom premieres on Thursday night on CBS.
