Things got pretty steamy at the Critics' Choice Television Awards on Sunday night when James Corden took the stage to present the award for Best Supporting Actress in a Comedy Series.

Allison Janney ended up winning the award ... and then some.

Um, holy lip lock! Allison must have been really touched by James's compliment there!

Though we can't say we were entirely shocked to see Allison smooching a random celeb.

But she has some ground rules.

But she clearly tossed those standards to the wind when she laid one on James — he and his lovely wife, Julia, have been married since 2012. Whoops.

But as a writer for Bustle points out, "The two actors seem to be old friends — maybe it's because they're on the same network — so I'm sure it will be cool with Corden's wife."
