American actress Kate Hudson is said to be eager to make her debut on the West End stage, after she got a taste for theatre playing in new movie musical Nine.

Hudson, 30, said she would love to appear onstage in London, but insists she would only consider a theatre role if her five-year-old son Ryder was happy to move to the UK.

"This (London) is one of my favourite cities, here and New York. (A stage play) would be fun. I mean, I'm down for anything, just as long as it's the right opportunity and timing for my family," the Daily Express quoted her as saying.

"You know, it's hard when you have a kid to move around. Your decision-making process and things like that becomes a lot harder, but I would never shy away from something like that... in the right circumstance," she added.
