It looks like Katy Perry and John Mayer isn’t the only Hollywood couple rumored to be splitting.

The gorgeous Kate Hudson might be on the outs with fiancé of nearly three years, Muse’s Matthew Bellamy.

The rumors were sparked by Hudson on Tuesday night when she showed up solo at Bulgari’s Decades of Glamour bash at L.A.’s Soho House sans her hard-to-miss 9-carat engagement ring.

It turns out though, their rock-and-roll relationship has been on the rocks for a while.

In December the couple and their 2½-year-old son spent time together in Austrailia where his band was playing. They spent Christmas in the U.K. with Bellamy’s family, skipping Goldie Hawn’s annual Christmas getaway in Aspen.

Since then, Hudson has been spotted family and friends, but not with her fiancé.

As far as their wedding, it seems to be postponed.

“Kate and Matt have been on the rocks for some time,” a source said. “They’re not in a great place.”

The New York Daily News reported the pair had “drifted apart,” earlier in the week prompting the rumors. Bellamy’s rep didn’t return its request for comment, while a rep for Hudson said, “It isn’t true.”
