She kissed a girl and she liked it! Katy Perry reportedly enjoyed the kiss that Miley Cyrus planted on her during the 'Wrecking Ball' singer's L.A. Bangerz Tour stop on Feb. 22.

“It was in the heat of the moment, and Katy is super cool with it because it was just a fun moment,” an insider reveals to HollywoodLife about the smooch, which appeared to take Perry by surprise.

“It’s not a big deal," the source continued. "It wasn’t planned; it was something that people have seen and she thinks it was actually super cool.”

While we're not surprised that Perry is so chill about the lip lock, she did seem to be taken aback when Cyrus went in for the kill. While singing 'Adore You,' Cyrus jumped off stage and unexpectedly kissed the 'Dark Horse' singer on the lips, and Perry immediately jumped back and stuck her tongue out.

However, if the source is to be believed, Perry was just simply caught off-guard -- but actually loved the moment.
