Allison Janney responds to Olivia Munn and Chris Pratt dating rumors (Exclusive)

Allison Janney had nothing but praise for how Olivia Munn and Anna Faris are handling the rumors that Munn is dating Faris' ex, Chris Pratt.

ET's Keltie Knight spoke with the SAG Award nominee on the SAG Awards red carpet Sunday night, where Janney said there is still a positive relationship between Pratt and Faris, her co-star on Mom.

"Chris and Anna, from my point of view, still love and respect each other very much," Janney said of the couple, who split in September.

"I think they would be happy, she would be happy for him to find someone, and she has found someone," she added, referring to Faris' current boyfriend, cinematographer Michael Barrett.

Munn tweeted a text exchange from earlier this month between herself and Faris Sunday, writing, "Hey there! Sooo... I would never respond to random tabloid stories, but since we know each other I wanted to reach out to you personally to tell you the story about me and Chris dating has 0% truth."

She continued, "I'm sure you already know it's not true, or maybe didn't care either way, but I just wanted to reach out personally to tell you it's not true."

Faris seemingly responded positively, writing back, "Oh my god-this town is so f**king crazy-you are so sweet to text-I love you-having said that if you were my new sister in law I would be thrilled!"

In response to Faris' reply, Janney said, "That sounds like my Anna, she's the coolest girl."

The Mom star continued, "They're just lovely people. And Olivia's a lovely person too, so I'm glad they didn't let a tabloid or whatever...I'm glad they put out the fire before it got out of hand."

Meanwhile, Janney is on track for an Oscar nomination this Tuesday for her role in I, Tonya, and is deeply touched by the possibility.

"I could start to cry right now. It's an actor's dream," she said. "That is the pinnacle. That is what I thought had eluded me and here it is coming at a time, a very unexpected time for me, with a movie that my dearest friend wrote for me. Everything that's come out of this experience is just, heavenly."

"I would be incredibly excited, over the moon to get a nomination in that world."

But Janney isn't planning on stopping at an Oscar nomination and resting on her laurels.

"I just want to keep working, looking for great scripts, that's what excited me about this, I, Tonya," the 58-year-old said.

"I'm coming up on my 100th episode of Mom, which I continue to love to do," she added. "And we're celebrating that next weekend with Anna. So I'm really proud of that, so we'll see what's next. I'm open to anything."

"Anything" could also include a West Wing reunion or reboot. Janney was spotted on her co-star Joshua Malina's instagram for the The West Wing Weekly podcast, and noted that the Bartlet administration seems to be getting together pretty often.

"We've all been hooking up a lot lately, running in to each other," she said. "I'm never to busy for Aaron Sorkin and the cast of West Wing, I love them."

"We all need something to believe in. I'm in. If Aaron said jump, we'd all run," she added, referring to the possibility of a reboot.

It seems like if Janney wants to do something, she will. That includes rocking a silver sequin long sleeved, high neck gown on the red carpet that makes her feel like a downright boss.

"I tried this on. It's by Yanina Couture. I think the designer, after what was going on in Hollywood, she wanted to create a dress that was empowering and beautiful, and to me this felt like an incredibly empowering dress," Janney said.

"[It's] like my suit of armor. I'm Khaleesi's warrior shaman or something. I just feel like, you can't touch this!" she added.

But she admitted there's one accessory missing.

"No bird today, I wish I had the real guy, Little Man [from I, Tonya], but I don't know how he would do on a red carpet. He would probably fly away," she laughed. (She sported a fake bird on her shoulder in homage on the Golden Globes stage two weeks ago.)
