Hackers XXXploit squeaky-clean Bieber

Justin Bieber fans looking to check out the 16-year-old singing sensation on YouTube yesterday were left panting — for all the wrong reasons.

Hackers redirected the mop-topped crooner’s legions of admirers to porn sites, while also targeting iTunes and Wikipedia.

Besides replacing the squeaky-clean Canadian with hard-core smut, the hackers sent tweens into a panic with a pop-up that falsely claimed their idol had died in a car crash.

The cruel hoax came as Bieber’s “Baby,” featuring Ludacris, closed in on Lady Gaga’s “Bad Romance” as YouTube’s most-watched video ever, with more than 230 million hits.

Pranksters from the notorious 4chan bulletin board were suspected, based on earlier capers that included spreading an ugly rumor that made “Justin Bieber syphilis” last month’s fastest-growing Google search.

Reports said the hackers exploited a security lapse that let users put malicious code in Bieber videos’ “Comments” section.
