After getting her hair darkened at Juan Juan Salon, Miley took a few hours to go shopping with her mother on Robertson on Saturday. Hope they found some nice stuff!





From there, the teen queen headed over to the studio so that the teen queen could rehearse her upcoming Today Show performance. Despite the long day she'd put in, Miley's spirits appeared to be as high as ever - just wait 'til you see how much fun Miley's having horsing around with her background singers!





And don't forget that even after all that activity, Miley still wasn't through her weekend to-do list - where does she get the energy?
