Miley forgets lyrics and makes a Lady Gaga dance

On the 29th November ,in Georgia, for a show of Wonder World Tour, Miley forgot a part of the lyrics to "When I Look At You" (@ 1:07), and then near the end you can realize, she turns to the side of the stage, probably playing with someone of the band, or backstage, and makes a quick little dance with her right hand. It's an imitation of Lady GaGa, in her new video "Bad Romance" (@ 2:25).
