What’s one sure fire way of pissing off one of the most powerful women in the world? Canceling an appearance on her daytime show……via E-MAIL!!

Kanye West was scheduled to appear on The Oprah Winfrey Show, however according to sources, the rapper decided to bail out on the big O and cancel his appearance on her show via a short e-mail.

Oprah‘s team had arranged a rooftop location for Ye’s performance and Oprah “was going to ask Kanye everything” when he sat on her couch.

But now that he’s canceled the gig, an insider says that “Oprah is not happy” due to the fact that all of the arrangements had been made.

Bummer!
