Ouch! After Katy Perry went on an Aussie TV show to say that she pulled away from Miley Cyrus when the singer tried to slip her the tongue in their kiss-seen-round-the-world because "God knows where that tongue has been," Miley has retaliated, rather meanly, on Twitter.

John Mayer and the fact that he was a bit of a serial tomcat (no pun!), dating lots of Hollywood leading ladies prior to Perry.

She then tweeted a fan drawing of the kiss and told Perry to stop denying that she loved it, which was kinder and gentler, but won't take the sting off her prior tweet.
