We'll have to wait until tomorrow night to see the most highly anticipated episode of Glee yet (the Britney Spears episode, naturally) but we've got a sneak peek of Heather Morris, aka Brittany, wearing some of Spears' sexiest looks from the past!

Wearing the glitterly nude bodysuit from "Toxic", her sexy "Slave 4 U" snake from the VMAs and of course, the skin-tight red pleather suit from "Oops I Did It Again", Heather could never fill her idol's shoes, but she certainly can fill out those costumes! Dayum!

And we're not the only ones who can't wait for tomorrow night's episode.

"Can't wait for GLEE tomorrow night," Britney tweeted, adding that "I'm going to tweet along as it airs on the West Coast so we can watch together. -Brit"

We'll see you then!
