Are Kate Hudson and fiance Matthew Bellamy calling it quits? Hudson is fueling recent rumors by stepping out in public recently–and frequently, too–sans her engagement ring.

PEOPLE magazine reports that the two aren’t in the greatest place right now.

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

In December Hudson and Bellamy, along with their 2½-year-old son Bingham, were together in Australia. Bellamy’s band Muse was performing there. They spent Christmas in the U.K. with his family, and skipped out on Hudson’s mom Goldie Hawn’s annual Aspen Christmas getaway.

Since then, Kate Hudson has been spotted out and about with family members and friends, but noticeably not with Bellamy. Kate has been in L.A., New York and at the Sundance Film Festival in Park City, Utah, where she promoted her film Wish I Was Here–but her significant other was nowhere to be seen.

On Tuesday night, Hudson showed up solo at Bulgari’s Decades of Glamour bash at L.A.’s Soho House, as seen in the video clip above. She wasn’t wearing her 9-carat engagement ring.

The source claims neither Kate Hudson nor Matthew Bellamy has moved out of their shared home.

The couple had a bit of a whirlwind romance, then became engaged in April of 2011. Just three months later they welcomed their son.

It was just about a month ago that Kate Hudson was a guest on Live With Kelly and Michael. When the hosts asked her about her and Matthew Bellamy’s wedding plans, she said “No, I’m planning nothing right now. I’m so busy, we’ve been so busy, and it’s been great. I come from an unconventional family – my parents aren’t married. So there’s a part of me that goes, ‘If I’m going to do it, I’m going to do it right’ … So, no. Not anytime soon, no.”

It sounds like something is amiss with Kate Hudson and Matthew Bellamy’s relationship. Might they be doing okay but simply not moving forward toward marriage? It’s certainly not unusual for these celebrity couples to become involved, have children and then question their relationships. Hopefully the two are able to create a loving and stable life for their son Bingham, whether they opt to tie the knot–or not.
