LONDON, May 6 (UPI) -- Miley Cyrus is finally back in action, twerking and tongue-wagging her way through the London leg of her Bangerz Tour at the O2 Arena on Tuesday.
The 21-year-old singer spent much of April recovering from what was described as a "severe allergic reaction" to antibiotics, forcing her to postpone a series of U.S. tour dates.
