Scarlett Johansson engaged

Actress Scarlett Johansson is engaged to be married to her journalist boyfriend Romain Dauriac.

Dauriac, who co-owns an independent advertising agency, proposed to 'The Matchpoint' star.

Her representative has confirmed the news, but did not disclose when it occurred, reported CNN.

"They haven't chosen a date for the wedding," she said.

Johansson, 28, was spotted wearing the diamond stunner earlier this week while promoting her new sci-fi movie 'Under the Skin' at the Venice International Film Festival.

The actress was previously married to Ryan Reynolds but they divorced in 2011. Reynolds later married Blake Lively.
