Another special guest that will be joining the TV personality on the road is her best friend and "CBS This Morning" anchor, Gayle King. The two, who have been friends for decades, have always been very open about their friendship. In the September issue of Oprah's "O, The Oprah Magazine," the producer revealed the one thing that could have caused a rift between the two of them. For her part, King has also spoken about the kindest thing that the former "Oprah Winfrey Show" host ever did for her.

"Oprah's 2020 Vision: Your Life in Focus" begins Jan. 4 in Fort Lauderdale with Lady Gaga serving as the night's special guest. Tickets to all dates can be purchased at WW.com/Oprah or on Ticketmaster.
