Is Lady Gaga's Fame tour still on or what?

There are a lot of rumors floating around on the internet and through my friends, and it’s really hard to distinguish between fact and fiction. I’ve heard she called of the tour with Kanye, it’s dead, oh no, she’s still touring but without him, oh it’s off completely.

There’s nothing on her official website until March 2010. That’s an awfully long time to go without any appearances.

Also, if you have any reliable sources that mention Houston specifically, that would be AWESOME! <3

One more thing: I don’t need any jokes about Lady Gaga or any “Who is that?” questions. Those are for chatrooms and google. THANKS!
