A day after confirming that they had called after their engagement, the newly single actress was spotted out in Los Angeles for an evening with some gal pals.
On Tuesday, Hudson's rep told People magazine, "Kate and Matt have been separated for some time now. Despite this, they remain very close friends and committed co-parents."
The couple had been together four years and became engaged in April 2011, with son Bingham born just a few months later that July. The couple never wed.
On Wednesday morning, the Muse singer tweeted that the breakup was "for the best" and seemed ready to talk about other things, like his new album.
Love all of you guys! We're both very happy, it's for the best. Thanks for your kind words. Now about that new album... — Matt Bellamy (@MattBellamy) December 10, 2014
