Michael Jackson's family is furiously trying to uncover the person responsible for leaking playful home video footage of the King of Pop's children online.
The Thriller superstar, who died last June (09), spent years shielding his three kids from the spotlight, making them wear veils to cover their faces whenever they went out.
But Paris, 12, and her eight-year-old brother Prince Michael II - aka Blanket - have recently become unlikely internet sensations after footage of the pair joking around and singing for the cameras appeared on the internet.
Nine video clips, including one showing Paris rapping, were posted around the web earlier this month (May10) but many have since been pulled from popular video-sharing websites like YouTube.com after Jackson family members contacted them to make complaints.
Now the late singer's father, Joe Jackson, is looking to track down the source of the leak so they can be held responsible for their actions.
He tells PopEater, "We don't know who (the hacker) was but we're trying to find out."
The star's eldest son, Prince Michael I, 13, is not featured in the footage.
