Kate Hudson Steps Out With Fiancé Matthew Bellamy in Los Angeles

Questions about the couple's relationship were raised after the actress was spotted without her engagement ring

What relationship trouble?

Kate Hudson and fiancé Matthew Bellamy, who are parents to 2-year-old son Bingham, were spotted out and about with a friend in Los Angeles on Friday.

The 34-year-old blond beauty looked casual chic in a pair of vibrant flower patterned pants and a T-shirt, while the Muse frontman sported a blue hoodie sweatshirt and khakis.

The couple has been engaged since 2011, but the actress has fueled reports that she's on the outs with the rocker after stepping out numerous times without her engagement ring. It's unclear if she was wearing her sparkler during this afternoon outing.

"They are OK," an insider told E! News last month. "They go through their ups and downs like every other couple. It's true that occasionally they don't spend as much time together as they would like—work pulls them apart from time to time. But they are working on strengthening their relationship."

Indeed, Hudson and Bellamy are committed to making their relationship work. "They do not see this as being a broken marriage that is beyond repair. Quite the opposite, in fact," the insider reveals about the A-list couple. "They are optimistic about the future and see that it will work out. They don't think for a second that they won't get through this. They love one another very much and will do what it takes to make it work."

Another source says that while Hudson wants to make it work, the actress also "misses being single."
