Allison Janney's romance with Philip Joncas is still going strong.

"He's pretty handsome," the Mom star gushed to me at the Sundance Film Festival premiere of her dramedy Tallulah.

Joncas, a production coordinator and artist who is 20 year's Janney's junior, was by her side on the red carpet at the Eccles Theatre. After taking photos together, Joncas stepped away as the seven-time Emmy winner continued on to do interviews.

Janney, 56, said they've been together for "about a year," but we shouldn't expect an engagement announcement anytime soon…or ever, for that matter.

"I don't believe in that institution," said Janney, who killed it on the carpet in tight green pants, a green sweater and suede snow boots.

Although Joncas attended the Minions premiere with Janney in July, their relationship hit the spotlight when he was her date to the Emmys in September.

Tallulah marks Janney's third film with Ellen Page. They also costarred in Juno in 2007 and most recently in 2013's Touchy Feely.

When Page arrived to the premiere, Janney and their director Sian Heber decided to have some fun and grabbed the petite actress and started swinging her into the air. At one point, they jokingly aimed Page at the photographers but stopped short of throwing her into them.

Janney wouldn't mind seeing Page pop up on Mom.

"I'll ask her," she said, before adding with a laugh, "She probably doesn't even know what it is."
