Michael Jackson's pop comeback has taken another unusual turn - his new track features 50 CENT and his G-Unit talent. The superstar, who last week signed British novelty hit king GUY HOLMES as his new manager, is embarking on a new sound with 50, LUCY PEARL and Dj Whoo Kid on the mixtape track TRIAL OF THE CENTURY. The track will be found on Whoo Kid's mixtape MJ UNIT - THE TAKEOVER, which will also feature five unreleased Jackson songs and 'mash-ups' of the THRILLER singer's classics with songs from the G-Unit catalogue. Jackson is working on his first studio album since 2001's INVINCIBLE in Bahrain, where he's now living.
