AceShowbiz - Kate Hudson and Matthew Bellamy have decided not to find out the sex of their unborn baby - as they want it to be a surprise. The actress is expecting a baby with the British rocker and the tot is due later this year, but they don't want to know whether it will be a boy or a girl ahead of the birth.

And Bellamy admits that although they are discussing possible names, they will leave it until the last minute to make a decision. He tells ET Online, "That (the gender) will be another surprise... We're starting to agree on names. Hopefully we'll think of something last minute."

Hudson is already mother to a son, Ryder, from her relationship with ex-husband Chris Robinson.
