ACTRESS Scarlett Johansson is set to marry Canadian actor Ryan Reynolds after more than a year of dating, according to People magazine.

"They're both thrilled," Johansson's rep Marcel Pariseau told People.

Reynolds, 31, who is currently filming "The Proposal" in Boston with Sandra Bullock, was reported to have just recently popped the question to Johansson. The couple have not set a wedding date.

Johansson, 23, the star of "Girl with a Pearl Earring" and "The Nanny Diaries," was photographed wearing a diamond ring at Monday night's Metropolitan Museum Costume Institute Gala in New York.

She is due to release her debut album, "Anywhere I Lay My Head" on May 20 with cover versions of Tom Waits songs and vocals from David Bowie.

Reynolds, who has starred in movies like "Definitely, Maybe" and "Smokin' Aces," was once engaged to Canadian singer Alanis Morissette.
