Kate Hudson stepped out solo for Bulgari's Decades of Glamour bash at Soho House in West Hollywood on Tuesday for a girls' night out.
While Hudson rocked some gorgeous accessories, she was spotted without one very important piece of jewelry: her 9-carat engagement ring. This comes on the heels of rumors that Kate and fiancé Matthew Bellamy may have hit a rough patch.
However, the 34-year-old actress seemed to be in a celebratory mood at the pre-Oscars bash.
"She looked really happy and seemed to be having a great time," one guest tells Yahoo. "She hung at a table near the back of the party and spent a lot of time talking with a group of girlfriends, including Naomi [Watts]. She was having a lot of fun."
Hudson stunned at the soiree in an Emilio Pucci white miniskirt and yellow silk blouse. She happily snapped photos with Watts, 45, and caught up with fellow "Glee" alum Dianna Agron, 27.
Last week, a rep for Kate denied that she and the Muse rocker were on the rocks, following a story in the New York Daily News on the matter. However, People reported on Wednesday that the couple has "been on the rocks for some time."
"They're not in a great place," claims the magazine's source, who also adds that they "are still living together. Kate is not giving up."
Hudson and Bellamy, 35, welcomed a son, Bing, together in July 2011 after getting engaged three months earlier.
In January, Kate explained on "Live With Kelly and Michael" that she wouldn't be getting married "anytime soon."
"I'm planning nothing right now," Kate said. "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.'"
