The pop beauty, who was forced to postpone the gig earlier this month due to illness, took to the stage at The O2 Arena to give one of her most provocative shows to date.
For the first 30 minutes, a leather-clad Demi writhed around as she belted out hit after hit.
From not-so-subtle album track Daddy Issues, where she sprawled herself on a chaise longue in suspenders to her 2015 hit Cool For The Summer, Demi left fans screaming for more and accompanying parents gasping in horror.
While sexualised stage shows is certainly nothing new in the world of pop, the show teetered on the brink of comical as Demi’s dancers vigorously simulated sex with each other before making a move on the superstar.
