The episode of Comedy Central hit South Park in which Eric Cartman sings Lady Gaga's "Poker Face" on Rock Band comes to life next week, with the release of Lady Gaga Pack 01 and a special track from Eric Cartman.

I said back in October that Eric Cartman's rendition of "Poker Face" deserved to be a real Rock Band track, and now it is. The special Cartman-voiced track will be available next week in the Rock Band music store, alongside four tracks from the real Lady Gaga, though I have my suspicions regarding exactly how real she is.

Suspicious bulges - that's all I'm saying.

Lady Gaga Pack 01 consists of "Poker Face," "Just Dance," "Monster," and "Bad Romance," meaning you can also relive the glory of LittleBadRomance.

Lady Gaga Pack 01 and Cartman's "Poker Face" will be available next week for the Wii, PlayStation 3, and Xbox 360.
