Last week Christina Aguilera said her fellow former Mickey Mouse Clubber/current contestant Tony Lucca had a "one-dimensional voice."

This week, Tony got to push Christina's buttons a little and show why he's still around to represent Team Adam with the BEST COVER EVER.

So what was the song he chose? Paying homage to ANOTHER Mickey Mouse Clubber, he rocked out Britney Spears' "Baby One More Time."

It was so good, I seriously considered buying the single from iTunes. I still might. Even Christina liked it...and you could tell she was off-put by the song choice.
