Kate Hudson, Matt Bellamy working on their relationship?

There were rumours that the 34-year-old actress and the `Muse` frontman had called off their engagement when Hudson was spotted without her ring, reportedly.

"They are OK. 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.," a source said.
