Kate Hudson thinks she is expecting a baby girl.

The 31-year-old actress - who already has seven-year-old son Ryder with ex-husband Chris Robinson - has already discussed names for the new arrival with her boyfriend, Muse rocker Matt Bellamy.

She said: "We have a couple of names but we're not telling anyone. People tell you so much about being pregnant it drives me nuts.

"It feels like a girl, but I don't know. Ryder thinks it's a girl."

The 'Bride Wars' actress also admitted she has no plans to marry 32-year-old Matt - who she has been dating for around nine months - because she no longer sees it as the "golden ticket" to a happy future following the breakdown of her union to Black Crowes singer Chris in 2006.

She told UK TV talk show host Graham Norton: "I don't like putting that sort of pressure on it and I don't feel it necessary to get married.

"I am 31. I already have one child and have had one divorce so it is not necessarily the golden ticket. I just want to be happy."

Kate's stepfather, Hollywood actor Kurt Russell, recently confessed the family were hoping for a girl to join the family.

He said: "It's fun having babies once again. And it's fun to watch them grow. It's fun to see what they're grasping. I think secretly we're all hoping for a girl."
