Way before he was "that guy dating Jennifer Aniston," Justin Theroux appeared in films like 'Mulholland Drive' and cowrote blockbusters like 'Tropic Thunder' and 'Iron Man 2.' And he did a bit of breakdancing in the beloved comedy 'Zoolander.'

In fact, one of things that may have attracted Aniston to Theroux were his 'Zoolander' moves, as Theroux explained on 'Ellen' Wednesday.

My girlfriend, I don't know if any of you guys know her ..." he joked to the audience. "Ever since she saw 'Zoolander,' she's been obsessed with making me break dance. Literally obsessed with it."

The catch is, Theroux will only breakdance if he has his special breaking shoes. So to make sure Theroux wouldn't have any excuses for not breakdancing on 'Ellen,' Aniston had sent over the special gold lamé Nikes, much to Theroux's surprise.

While Theroux cried out in horror when Ellen revealed the shoes to him, once the Rob Base classic 'It Takes Two' started playing, he had no problem strutting his stuff. What do you think? Pretty good for a 40-year old, right?
