Britney Spears' debut as a judge on Season 2 of "The X Factor" Wednesday was anticipated by many fans and peers -- including Ke$ha. The "Tik Tok" songstress took to Twitter to wish Spears well just before the premiere, tweeting, "Go kill em on X-Factor tonight honey boo boo! #GoodLuckBritney." Ke$ha was, of course, making reference to last night's other must-see series, TLC's "Here Comes Honey Boo Boo."

Though Spears' team reportedly banned all alcohol from the "X Factor" set, Spears revealed her beverage of choice when she graciously replied, "@keshasuxx My special juice @Pepsi helps me wiiin!! LOL When do I get to hear your new music?"

As "Honey Boo Boo" enthusiasts know, the titular tyke's "special juice," which the 7-year-old imbibed prior to a pageant on an episode of "Toddlers & Tiaras," consists of Mountain Dew and Red Bull.

Britney and Ke$ha previously collaborated on 2011's "Till the World Ends." "I consider myself a songwriter before and above everything else, so it's an honor to write for one of pop music's biggest icons," Ke$ha told MTV News last year.
