Kate Hudson has spoken for the first time about her relationship with Muse frontman Matt Bellamy.

The couple, who met at the Coachella festival in 2010, are expecting their first baby together later this year.

Appearing on The Graham Norton Show, Hudson paid tribute to the singer, but denied recent tabloid reports that they are engaged.

“I don't like putting that sort of pressure on it and I don't feel it necessary to get married,” she said.

Asked about dating a British man, Hudson replied: "I never thought I would notice the difference but there are a lot of differences, it's just a different way, he is polite and kind and so sweet."

The actress, who already has once child, Ryder, seven, with ex-husband Chris Robinson, added that hearing Bellamy's voice on the phone had “signed the deal for me”.

Viewers will be able to watch Hudson's appearance on The Graham Norton Show on BBC 1 tomorrow (January 28).
