Joaquin Phoenix is not only flexible — he's also engaged.

The 40-year-old actor was a guest on Late Show on Monday, and he surprised David Letterman with the news that he's getting married.

The revelation came after Phoenix told a story in which his fiancee, whose name he didn't mention, encouraged him to harness his "hog." Yes, you read that correctly.

The actor, who made a puzzling Late Show appearance in 2009 for the mockumentary I'm Still Here, proceeded to lie down on the stage on his back while grabbing his leg for some reason.

Phoenix then retracted his account the next morning while appearing on Good Morning America and Live! With Kelly and Michael.

Watch the unusual exchange unfold in the video below.
