Scarlet Johansson plans to marry her fiance, French journalist Romain Dauriac, sometime next month. 

The pregnant movie star was a guest at a private dinner hosted by Martha Stewart at her Hamptons estate and was overheard saying she's getting married in four weeks. The exact date and venue are being kept under tight wraps. It could take place in the Hamptons where they've been spending a lot of time, or possibly in Dauriac's native Paris. (Page Six)
