While making an appearance on The Ellen DeGeneres Show to promote his upcoming flick Wanderlust, Justin Theroux treated the audience to an impromptu breakdance, and you won't believe his moves!

The 40-year-old actor revealed to Ellen that his girlfriend, Jennifer Aniston, has “been obsessed” with getting him to breakdance, ever since she got a glimpse of his moves in the Ben Stiller comedy, Zoolander.

Theroux told DeGeneres of his special talent:

    "There is actually a rule that I have. I have a very particular pair of shoes which I breakdance in. Actually when my girlfriend I don’t know if any of you guys know her. She just recently celebrated a birthday and ever since she saw Zoolander she’s been obsessed with making me break dance. Literally obsessed with it. I break danced at a friends wedding. So she’s been saying when are you going to break dance? That’s when I sort of invented this thing."

He added, "Well, I have shoes my "breaking shoes" and if I don’t have my "breaking shoes" then I don’t breakdance, sort of full stop. We got home that night. It was late and she literally came out with a pair shoes. My actual "breaking shoes."

Luckily, Aniston had a surprise sent over to the studio for her man -- his special pair of "breaking shoes!"
