Fergie and fiancé Josh Duhamel are said to be getting married in California next month.

It is thought they will have the ceremony over the weekend of 9-11 January.

Nicole Kidman, 41, and Kate Hudson, who star with Fergie in big screen musical adaptation Nine, will apparently be among the guests.

Fergie, 33, and Josh, 36, have been dating for four years.

They announced their engagement last Christmas.
