It's here! Watch Britney's episode of Carpool Karaoke.

Not only do the two tackle Spearitual smashes like "Womanizer," "Oops!...I Did It Again," "...Baby One More Time" (complete with appropriate schoolgirl pigtails and cardigans) and "Make Me," but Brit Brit even gives us a half-second of Original Doll's "All That She Wants" — and even a brief lesson in some "MmMMmmYeahHhhHh"-ing.

Plus, some very cool and different aliases. Anita Dick, anyone?

It's all way, way too much!
