A simple two sentence press release is all the information offered by tour promoter Live Nation.

Ticket holders can obtain refunds at point of purchase. Tickets purchased online and via phone will be refunded automatically.

Could the tour have fallen victim to the backlash over Kanye West’s douchey behavior at last month’s MTV Video Music Awards?

And while Gaga has been defending Kanye in the press in recent days, even telling MTV that he feels “so f*#$*ing bad,” is it possible the pair have had a falling out?

Or does this have anything to do with those reports by MSNBC that Kanye will soon be seeking treatment for alcohol abuse?

Calls to Lady Gaga’s reps were not returned at press time.

Stay tuned.
