Lady Gaga and Kanye West cancelled their tour just weeks after it was announced, and now Gaga’s choreographer took to her Twitter account to address why. According to PerezHilton.com, Laurieann Gibson said it was due to “creative differences,” but also announced that the “Just Dance” singer will be going out on a tour of her own. Gaga later confirmed this, writing on her Twitter she’s still hitting the road in November and will officially announce it sometime this week.
