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.

While Perry was clearly making a joke and was largely complimentary about Miley during the rest of her interview, Cyrus' tweet was below the belt, addressing KP's recent split with 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.
