Sad news to report: Kate Hudson and her fiance Matt Bellamy have called off their engagement.

Months after rumors of a split began swirling, the 'Glee' actress and Muse rocker -- who are parents to 3-year-old Bingham Hawn Bellamy -- have announced the end of their four-year relationship.

"Kate and Matt have been separated for some time now," Hudson's rep revealed to PEOPLE. "Despite this, they remain very close friends and committed co-parents."

And that's not just lip service -- just a few short weeks ago, the pair attended Hudson's mom Goldie Hawn's 'Love In for Kids' benefit, looking totally amicable and even happy together (just check out the picture above). In Hollywood, where splits can get nasty quickly, it's super refreshing to see how well the two get along post-breakup. Goals, for sure.

In addition to her son with Bellamy, Hudson is also mom to Ryder, her 10-year-old son with ex-husband Chris Robinson.
