Oprah Winfrey doesn't need any extra star power to get people out to see her on stage -- but she's still calling in pals Lady Gaga and Jennifer Lopez to boost her upcoming Wellness Tour.
Oprah’s 2020 Vision: Your Life in Focus will feature one-on-one interviews with celebrities like Gaga, J-Lo, Michelle Obama and Dwayne "The Rock" Johnson, but the all-day events won't stop there -- they'll also include seminars, dance sessions with Julianne Hough and interactive demonstrations.
Gaga will appear at the tour kickoff in Orlando on January 4th.
