'Mom' On CBS: Anna Faris, Allison Janney Preview Their New Chuck Lorre Comedy

"Mom" on CBS is bringing Anna Faris and Allison Janney together.

The new sitcom from Chuck Lorre stars Faris as Christy, a newly sober single mom. This is Faris' first regular TV gig and "The House Bunny" actress said a combination of things drew her to the project.

"The script was so strong and so funny, the character was so complicated and dimensional and then obviously Chuck Lorre and CBS. You couldn't be in better hands." Faris told The Huffington Post on the red carpet of CBS's upfront presentation. "Then Allison came on ... it sounds like one of these actor soundbites that I'm about to tell you, but ... I would wake up and be really excited to go to work. Even though we have our dream jobs, basically it doesn't always happen."

Janney plays Bonnie, Christy's passive-aggressive mother who is also struggling with her own addictions. To say the relationship is complicated is an understatement. "What's great about our relationship is just how truthful it is," Faris said. "This is something that I'm sure any woman can relate to -- this very frustrating relationship."

After years on "The West Wing," a comedy was a welcome change for Janney. "I'd been looking for this scenario, this situation for my whole career," she said. "To get to do this schedule and have a life -- I mean, for all my years on "West Wing" and doing 18-hour days, I've given blood and I feel like I need a little blood put back in me."

Janney said she had no personal life while doing seven seasons of "The West Wing." "I am thrilled to not only get to throw my hat into the three-camera arena, [but] to get to act with in front of a live audience with all my years of theater and training and have it be a comedy with Anna and Chuck, it's really, truly a dream situation."

Watch two previews of "Mom" below. The new comedy airs Mondays at 9:30 p.m. on CBS this fall.
