Delevingne hung out with Jourdan Dunn and Rosie Tapner backstage on Sunday night. She was getting ready for Topshop Unique fall/winter 2013 runway show.
Jourdan started breaking out in dance. The two other models stood there, looking pouty as ever. Then Cara and Rosie joined her in the "Harlem Shake."
The model shook it out before the big show. They appeared to be having a good time. They didn't care if their hair got messy before hitting the runway.
The "Harlem Shake" has been taking the Internet by storm. The first video went viral on YouTube in early Feb. 2013.
This Internet meme is not to be confused with the "Harlem Shake" dance from 1981. The video typically begins with one person dancing alone to a song for 15 seconds while others are unaware of the person dancing.
Once the bass drops, the others join in for the remaining 15 seconds. Some join in with costumes or props. Some people find the videos stupid, while others find it hilarious.
Since the first "Harlem Shake" video debuted Feb. 10, 2013, others have been doing their own recreations. Some call this the next planking meme or "Gangnam Style" dance craze. It sure looks like Cara Delevingne is enjoying herself at London Fashion Week.
