What Jen wants, Jen gets!

There's plenty of things Jennifer Aniston loves about boyfriend Justin Theroux -- including his formidable breakdancing skills, which he first shared with the world in 2001's Zoolander.

"My girlfriend, I don't know if any of you guys know her…ever since she saw Zoolander, she's been obsessed with making me break dance," Theroux, 40 says on Wednesday's Ellen DeGeneres Show. "Literally obsessed with it. I break danced at a friend's wedding. So she's been saying, 'When are you going to break dance?'"

To rebuff Aniston's demands, the Wanderlust star "invented" a rule, he explains to Ellen DeGeneres. "I have my 'breaking shoes,' and if I don't have my 'breaking shoes,' then I don't breakdance."

Cut to Aniston's 43rd birthday on Feb. 11. "We got home that night," Theroux recounted. "It was late, and she literally came out with…my actual 'breaking shoes,'" and told her man to break dance.
