Katy Perry Twitter account hacked

Pop star Katy Perry has fallen victim to an Internet hacker, who took over her Twitter page and leaked an unreleased song.
The Roar hitmaker's account was taken over yesterday when a message going out to her 89 million followers read, "haha follow @sw4ylol #hackersgonnahack."
The user "@sw4ylol" is reportedly based in Romania and only started the account a few days ago.
The hacker also sent off a series of vulgar and nonsensical tweets on the 31-year-old singer's page.
The user wrote, "miss u baby @taylorswift13," which seemed to be an attempt to reignite a reported rivalry between the two entertainers.
