Steven Tyler Performes "Dream On" With Members of Stone Temple Pilots on American Idol Finale

Robert and Dean DeLeo of Stone Temple Pilots joined Aerosmith frontman and "American Idol" judge Steven Tyler on stage during tonight's (Wednesday, May 25) season 10 "Idol" finale to perform the Aerosmith classic "Dream On". You can watch video footage of their appearance below.

Despite Tyler's recent insistence that Aerosmith would play the "American Idol" finale, Aerosmith guitarist Joe Perry said in a recent online posting that the band was "never asked by producers" to perform at the event. He added that "Brad has a gig that night with (Experience Hendrix). It's not logistically possible."

Perry did write that Aerosmith is "looking forward to playing 'American Idol' next season when our new CD is out and we can prepare (for) a kick-ass show if they ask us."
