Allison Janney and James Corden had a very friendly exchange on stage at the Critics’ Choice Television Awards on Sunday.

The actress, 55, went in for a passionate kiss when the comedian and Late Late Show host, 36, presented her with the award for best supporting actress in a comedy at the fifth annual awards show in Beverly Hills.

“The award goes to, I think, one of the best actresses I’ve ever met,” the British actor said as he introduced the Mom star. (See the sexy exchange in the clip above.)

Looking utterly shocked after hearing her name, Janney stood up and headed to the stage, where Corden gave her a little bow before going in for an awkward hug-turned-lip-lock.

Janney grabbed the back of the funnyman’s head as they held each other in a close embrace, while receiving major cheers from the audience.

And the smooch caught the attention of the awards show host Cat Deeley, 38, who considered the stint the high point of the night because it “set the tone.”

“It’s like, ‘Oh that’s what this awards show is!’ It’s about celebrating people’s talent, but at the same time, let’s all have a laugh,” the So You Think You Can Dance host told PEOPLE. “Let’s have a glass of champagne, and let’s let loose a little bit and have a really nice time.”

Whether it was impromptu or staged, the blond Brit had a theory for why Janney slipped in the smooch.

“[Janney] just got back from London because she’d been promoting a movie. She was slightly jet-lagged, and she didn t think she’d win. So I don’t think she [had] a speech,” Deeley said with a laugh. “She was like, ‘S—, I’m going to have to tongue James Corden.”

Corden and Janney’s steamy moment wasn’t the only A-list kiss of the evening.

Funny gals Tina Fey and Amy Schumer also shared a hilarious embrace onstage at the 74th Annual Peabody Awards Ceremony at Cipriani Wall Street on Sunday in N.Y.C.

Fey, 45, said while presenting the 34-year-old comedian with a Peabody win, “Amy Schumer is killing it, as the agents like to say. Usually they are lying. But in this case it is true. Amy is killing it. She is the biggest deal in comedy right now.”
