One thing you can never fault pop singer Miley Cyrus for, is being boring. Her Bangerz Tour has certainly had tongues wagging (sorry!) for its raunchy stage antics and provocative costumes. But one person that clearly remains fully supportive is our ELLE Woman of the Year, Katy Perry, who was particularly affectionate at Miley Cyrus' LA show at Los Angeles' Staples Center on Saturday.

While performing her more slower-paced single, Adore You, Miley spotted her celebrity pal in the audience, and swooped down to plant a kiss on the lips of the 'Roar' songstress.

Other attendees included members of the Kardashian clan (Kourtney, Khloe and Kendall were in tow), Hilary Duff, Christina Aguilera, Nicole Richie, and even legendary actress Diane Keaton.
