Miley Cyrus kissed Katy Perry and she liked it

When Katy Perry's a fan, she has no problem showing it.

The 29-year-old pop star was just one of the celebrities in the audience at Miley Cyrus' "Bangerz" concert in Los Angeles on Saturday, but she was the only one who got to kiss Cyrus and then tell about it.

As evidenced by a photo Cyrus shared on her Twitter account, the two songbirds locked lips while Cyrus was still up on stage.

Cyrus, 21, was in the middle of performing "Adore You" when Perry's lips apparently started calling to her.

"I just kissed a girl, and I really liked it a lot," Cyrus told the audience.

Perry seems to have enjoyed it, too, as she tweeted a photo of her shocked face after with the caption, "I adore you, Miley Cyrus"

From where he was sitting, rocker Joel Madden enjoyed the performance.
