Justin Theroux has revealed his girlfriend Jennifer Aniston is ''obsessed'' with his break dancing.

The 'Friends' actress has been keen to get the 'Wanderlust' actor - who she has been dating since last year - to breakdance for her ever since she saw him play the Evil DJ in 2001 movie 'Zoolander'.

Speaking on the 'Ellen Degeneres Show', he said: ''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 breakdance. Literally obsessed with it.

''I breakdanced at a friend's wedding. So she's been saying when are you going to breakdance?''

Justin admits he uses a ''very particular pair of shoes'' with which to perform such moves, and when the pair got back from celebrating Jennifer's birthday recently she made him dance for her.

He added: ''After the whole thing. She said, put on the shoes, breakdance.''
