Katy Perry has firmly denied assault allegations made by actress Ruby Rose in a forceful statement, Wonderwall.com can report. The pop star's response came hours after Rose publicly accused the "Firework" singer of s***** assault in a series of social media posts. Perry's representative pushed back strongly on the allegations, rejecting any suggestion of wrongdoing. "The allegations being circulated on social media by Ruby Rose about Katy Perry are not only categorically false, they are dangerous, reckless lies," the "Roar" hitmaker's rep told TMZ.
