Scarlett Johansson has sparked rumors she is engaged.

The 28-year-old actress - who was previously married to Ryan Reynolds for two years before their divorce was finalized in June 2011 - was spotted with a huge diamond ring on her engagement finger while strolling around New York with her French boyfriend of three months Romain Dauriac.

The Hitchcock star was sporting a pear-cut diamond ring as she wandered around the East Village with the 30-year-old journalist, according to the MailOnline.com.

The couple began dating in November after being introduced by mutual friends, just weeks after the actress split from her boyfriend of one year Nate Taylor. Scarlett was previously said to have been desperate to keep her relationship with Romain, who is the former editor of French urban art magazine Clark, and is now the manager of a creative agency - under wraps since they met.
