Kate Hudson and her rocker fiancée Matthew Bellamy may be over. Several entertainment outlets are reporting that the couple has hit some rough seas after four years of dating. A source told Us Weekly, "They realized they are in different places in their lives. They grew apart. It's not good right now. They're taking time apart to try to make things work." Another insider told People, "Kate and Matt have been on the rocks for some time. They're not in a great place." Matt and Kate are reportedly still living together and Kate is apparently not willing to give up on the relationship. They met in April 2010 at the Coachella Music Festival and were engaged a year later. They have a two and a half-year-old son together named Bingham. Back in December, the family spent Christmas with the Muse band member's family in the U.K. but have not really been seen together in public much since then. Most recently, Kate attended Bulgari's Decades of Glamour event in L.A. on Tuesday night solo and without her engagement ring on.
