Talkshow host Ellen DeGeneres had a bit of a surprise for actor Justin Theroux when he appeared on her show this week.

Theroux went on 'Ellen' to promote 'Wanderlust', a new film starring both him and his famous girlfriend, Jennifer Aniston, and mentioned his break-dancing hobby.

After saying Aniston was "obsessed" with it, Theroux mentioned he could only break-dance if he had his special shoes for it.

Cue DeGeneres producing a bag containing the shoes and a note that said:

"Ellen - I thought Justin might need these. See you tomorrow, Jen."

Being a good sport, Theroux put on the shoes and treated the audience to a bit of a show.
