Scarlett Johansson and Ryan Reynolds are set to become man and wife, having announced their engagement.

The couple has been dating since February 2007, shortly after Blade: Trinity star Reynolds broke off his engagement to singer Alanis Morissette.

The actress's representative Marcel Pariseau confirmed the news to People revealing: "They're both thrilled."

Scarlett is set to release her album of Tom Waits covers Anywhere I Lay My Head later this month.
