Rumors are flying the Britney's gonna show up to the Nickelodeon Kids' Choice Awards tonight and we are absolutely praying it's true!

Word on the street (well, online, really), is that Brit may not only show up on the orange carpet but that should could actually perform! Speculation is that Brit was rehearsing at Alley Kat studios (above photo) last Monday for that very reason!

Publicists for the show, which will be hosted by Jack Black, have said, "The show is always full of surprises... You never know who'll show up."
