The King of Pop may have parted from this world, but that isn’t stopping Vegas from celebrating his birthday. On Aug. 29, Cirque du Soleil and the Estate of Michael Jackson are celebrating his birthday with a day-long part at the ONE Theatre at Mandalay Bay. The celebrations include a book-singing with Forbes senior editor/Michael Jackson Inc. author Zack O’Malley, a behind-the-scenes doc of MJ’s new XSCAPE album and more.
