Britney Spears' one-time love rival is hoping to launch her pop career with a little help from super-producer Pharrell Williams. Shar Jackson, the mother of two of Kevin Federline's kids, is hoping to release her first album later this year (07), and she's calling on the studio skills of Williams. She says, "I've got everything crossed. I'd really like to work with Pharrell." The producer needs a career boost himself; his last album In My Mind was a flop and he's now considering remixing tracks with The Roots star uestlove and giving the project another chance on the charts.
