We've already seen what the masterminds behind "Glee" can do when they pay homage to blond pop stars (see: Madonna and Lady Gaga), but now it's time for the highly anticipated Britney Spears episode, which premieres Tuesday night (September 28). With Spears onboard to make an appearance in the episode, it's shaping up to be one very exciting episode — and it even had the cast freaking out.

In the months since it was rumored that the hit Fox show would pay tribute to Spears, there's been so much information floating around about it that we here at MTV News thought we'd round up the most salient tidbits regarding the episode, which is already rumored to have a sequel sometime next year.

Judging by preview clips, it appears Brittany and Santana hit up their local dentist, played by John Stamos, to get their hands on some anesthesia. From there, the girls go on a trippy ride through Brit's catalog, with some appearances by the pop princess herself. Show creator Ryan Murphy has called the episode "hallucinogenic."

The cast will be doing six of Britney's biggest hits all while resurrecting her most iconic costumes, including the "Oops ... I Did It Again" red-leather bodysuit; the bejeweled (and nearly naked) "Toxic" look; the "I'm a Slave 4 U" green bikini, complete with snake; Madonna and Brit's "Me Against the Music" menswear-inspired suits; the "(Baby) One More Time" schoolgirl uniform; and, finally, a stirring rendition of "Stronger."

Spears herself has been keeping her fans updated about the episode, and she will be live-tweeting during the show's West Coast airing. The bottom line, according to Amber Riley, is that the episode will live up to all of the hype. "I can tell you it's going to be a really great episode and you're going to love it," she said. "And they're doing the big hits from Britney."
