Kate Hudson won’t know when she and fiancé Matt Bellamy will wed “until they day they get married”.

The actress and the Muse frontman have been engaged since April 2011. The new parents also welcomed their son Bingham into the world last July.

Kate and Matt still don’t have a wedding date set.

"I think until the day we get married, the answer is going to be, ""We have no intention right now of getting married."" And then you""ll find out we got married," she told USA Today.

"We have an idea. It""s starting to formulate but it""s a timing thing. But honestly, right now, Matt is touring. [My son with Chris Robinson] Ryder is in school. I""m working.”

Kate and Matt are excessively busy in their careers.

With her hectic professional schedule collapsed with parenthood, Kate admits that she doesn’t often schedule in rest.

"I sacrifice being exhausted,” she said.

“I [arrived in New York] last night late and I""m leaving after this [to go back to Los Angeles]. I""m gone for less than 24 hours. That""s what you do.”
