Miley Cyrus kisses Katy Perry at Bangerz Tour Concert in LA

Miley Cyrus kissed Katy Perry during her performance in 'Bangerz Tour' concert in Los Angeles on Saturday.

The 'Wrecking Ball' singer got down from the stage and locked lips with Perry, who was sitting in the front row, People Magazine reported.

The 21-year-old pop star kissed Perry only for a second but seemed to catch her by surprise. The 'Teenage Dream' singer backed away quickly and put her hand over her mouth.

Perry later tweeted a photo of the aftermath and told Cyrus that she adores her and hopes Cyrus knows this.
