After eight years of marriage, Fergie and Josh Duhamel are going their separate ways. The former couple, who tied the knot in Malibu in January 2009, are the parents of 4-year-old son Axl. Though they have now parted ways, the stars are amicably coparenting their little guy. "They are still very friendly and get along," the insider tells Us. The news of the separation comes a week before the release of Fergie’s second studio album, Double Dutchess.
