Hollywood actress Scarlett Johansson and actor Ryan Reynolds, who have been silently dating for over a year, decided to take their relationship to the next level and got engaged, Johansson's rep confirmed in a statement to People.

"They’re both thrilled," Johansson’s rep Marcel Pariseau was quoted by People as saying.

However, according to E!Online, a source close to Johansson claims that the couple have actually been betrothed "for a little while," and they have kept the engagement on the down-low because "they want to keep things private."

The two started dating in the spring of 2007, shortly after Reynolds, 31, broke off his engagement to singer Alanis Morissette following a four-year relationship. Scarlett also dated her "Black Dahlia" co-star, Josh Hartnett, for about two years until the end of 2006.

Earlier this year, the 23-year-old actress was spotted shopping for wedding dresses in Los Angeles, but immediately rejected engagement rumors, explaining that a member of her family was getting married, not her.

The couple is next expected to attend the Metropolitan Museum Costume Institute Gala in New York, where Johansson will undoubtedly debut her ring.

Reynolds is currently filming "The Proposal" in Boston with Sandra Bullock, while Johansson can next be seen in Woody Allen's "Vicky Cristina Barcelona" and the Drew Barrymore-produced "He's Just Not That Into You." She most recently starred in "The Other Boleyn Girl" alongside Natalie Portman.
