Scarlett Johansson found fame in the hit film Lost In Translation
US actress Scarlett Johansson and her boyfriend Ryan Reynolds have announced their engagement.
The star's publicist, Marcel Pariseau, confirmed the news but says the couple have not set a wedding date.
The 23-year-old showed off her engagement ring on Monday night at New York's Metropolitan Museum of Art's Costume Institute Gala.
The couple started dating last year after Reynolds, 31, split up with fiancee Alanis Morissette in 2006.
Johansson's recent film credits include The Other Boleyn Girl, The Nanny Diaries and Lost in Translation.
Ryan Reynolds has appeared in movies like Smokin' Aces, The Nines Chaos Theory and Definitely, Maybe.
