Mouse-to-mouse resuscitation: Not that Britney Spears exactly NEEDS a career boost, but next-gen Disney pop princess Selena Gomez is planning a special tribute to the former Mouseketeer in Gomez's upcoming concert tour. The younger Mouse Factory alumna, who's also snagging headlines with boyfriend Justin Bieber, told MTV News she plans a "mash-up of all her songs" but won't try to mimic the Britster's slinky dance moves. No comment, as yet, about pythons.
