Wild child Miley Cyrus is known for her antics & controversial bad girl behavior.  This time she pulled a "Britney-Christina-Madonna" moment by kissing a girl. Can you guess who the infamous girl is?

While performing in concert at her Bangerz Tour at The Staples Center in LA over the weekend, Miley's raunchy costume choices & sexy sets weren't the only talk of tinsel town.  There was a famous guest in the building, y'all may've heard of her...Katy Perry, the girl behind "I Kissed a Girl".

Madonna is the queen of shock value & many singers try to emulate her. Christina Aquilera, Britney Spears, Lady Gaga & now Miley Cyrus all seem to have taken a page out of Madonna's how to have shock value instruction guide.  Since Miley recently performed with Madonna on Mtv Unplugged, I wonder if she gave her a tip of what to do next for shock value.

Well it appears Miley Cyrus & Katy Perry are big fans of each other as witnessed by their liplock during Miley's performance of her new single "Adore You". And after, Katy tweeted "I adore you Miley!" Hope John Mayer doesn't get jealous...
