Aretha Franklin, Angie Miller, Adam Lambert, half-naked Jessie J rock 'American Idol'

And then Jessie J, whose blouse exposes quite a bit of her anatomy, shows up to perform "Domino" with Miller. They're lots of fun to watch, both are vamping it up as Miller seems to be having the time of her life, singing with her idol.

The three of them should go on tour together; they wouldn't even really have to sing, they could just jump around on stage. Funny, Lambert's the quiet one in this group.

After that they do a brief tribute to Jackson, since this is his last season on the show after 12 years -- although none of this season's judges are coming back, if you believe the rumors. He's a good guy, even if sometimes he lived in his own world. He needs to write a book about everything he's seen.
