Michael Kovac/WireImageKate Hudson is wearing quite the impressive ring on that finger, but it isn't her engagement bauble from fiancé Matthew Bellamy.
The actress looked radiant as she celebrated the Little Black Dress Collection for Ann Taylor at Chateau Marmont on Tuesday in Los Angeles.
The 34-year-old star donned a formfitting one-shoulder LBD gown, which featured a high-slit. The Oscar nominee wore her wavy blond locks down and completed the sexy ensemble with white pumps as well as the familiar bling on her left hand.
Hudson previously sported the dazzling sparkler to BVLGARI's Decades of Glamour event on Feb. 25 and she also paired it with her sizzling white Atelier Versace dress at the Oscars.
After more than a month of are-they-or-aren't-they, E! News learned exclusively that the actress and the Muse frontman are still together and doing whatever necessary to make their relationship work.
"Kate and Matt spent several weeks apart, and the time away was good for them as they've been trying to figure things out," a source told E! News in March. "They didn't want to end their relationship, so they took a step back for awhile to let things cool off."
The source continued: "They had been in a rough patch and things weren't going well. They've been to counseling and decided they both would like to stay together for now. Kate has never been traditional and she doesn't know exactly what their future looks like."
The couple has one child together, 2-year-old son Bingham.
