LawdT, the amount of reading, gathering, scalping, and dragging we'll be able to do if We R Superstars is a Gaga + Britney collab. (and ESPECIALLY if it smashes) AND the amount of life I'd get from it. The only thing that would make me any happier with Gaga than that is if The Greatest Thing were to be officially released.
The Gaga and Britney stanbases will be empty for a month if it happens, too, because all of us will have punched out the day after it releases. It'd be worth it, imo. I would be ecstatic for the next month anyway.
