Icelandic singer Bjork is working on collaborations with Timbaland and ANTONY HEGARTY for her new album. The PLAY DEAD star is promising to reinvent her sound yet again on her, as yet untitled, sixth studio album, with hip-hop and R+B beats. She says, "I took these tracks and worked on them further." With her spokesperson adding, "I hear that she has taken them to another level." The 41-year-old is also collaborating with MARK BELL, BRIAN CHIPPENDALE and CHRIS CORSANO on the LP set to be released later this year (07).
