You know, we can remember sitting in Ballroom 20 during the Comic-Con 2011 panel wherein 'Glee' series creator Ryan Murphy promised the show would become more about the interpersonal drama between the character rather than flashy guest stars and tribute episodes.  Yet here we are, only one episode deep into 'Glee' season 4, and it's time for another Britney Spears tribute!  Love or hate the new season, it's hard to deny the full-length performance of 'Hold It Against Me" at least has sex appeal!

Last week's 'Glee' premiere "The New Rachel" introduced fans to a world divided between Rachel (and now Kurt!)'s escapades in New York, and the familiar sights of McKinley High, but what better way to make things feel like home than with another Britney Spears tribute episode?  Though it's unlikely that Britney herself will appear this time around, we've a fine replacement in Brittany S. Pearce, who wiggles her way through a performance of "Hold It Against Me" in the latest clip.

Of course, Brittany won't be the only one tackling the dulcet tones of the current 'X-Factor' judge, as Rachel Berry will get in on the action once more to deliver a sexified rendition of "...Baby One More Time" for her dance class.  Why couldn't we have video of that?

In any case, get a sneak peek at "Britney 2.0" in the clip below, and tell us what you thought of 'Glee's season-opener in the comments!
