When the Bangerz Tour stopped at the Staples Center in Los Angeles, many stars came out to watch Miley Cyrus perform. But some were not prepared for her controversial show.

For one, Katy Perry, seated front and center, unexpectedly received a kiss from the show’s star.

Joel Madden, who attended the show with wife Nicole Richie, tweeted, “That @MileyCyrus puts on a great show.”

Another singer, Max George from The Wanted, also enjoyed watching the show. “Am I tripping?…no… @mileycyrus is absolutely smashing it!!” he said.

Even though it seemed like a lot of the A-list crowd had a blast, other fans did not seem as happy—comparing it to a strip show—and even said it was “uncomfortable to watch”.

“Miley was impersonating a stripper pretty much and threw money in the air. You can see she is having fun with herself but it's just too far,” an insider shared. “It's sad that she has to act like this to get attention.”
