French trio heel dancers Yannis Marshall, Arnaud and Mehdi dance to a Beyonce medley in short costumes.
Getting their legs out may not have been for Simon, who buzzed them but the other judges seemed to love it, when they got up dancing.
After being confronted by Ant and Dec and the other judges, Simon said he “didn’t think it was very good”. However, Amanda backed them up saying “your passion and commitment is sexy”.
