Scarlett Johansson is after sparking rumours that's she's intending to put a ring on it again after being spotted walking around New York with a massive sparkler on her engagement finger.

Having previously being married to Ryan Reynolds for two years before their divorce in June 2011, Johansson was papped with her French boyfriend of three months Romain Dauriac strolling around a sunny and chilly NYC with a very obvious bit of bling on her ring finger. Eagle-eyed diamond know-it-alls have said it's a pear-cut diamond ring, which is something because we can barely make out the ring in the photos let alone see what shape it is.

ScarJo and the journalist apparently started dating in November after being introduced by mutual friends, just weeks after she 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. It's a clear change from the high profile relationships she's been in before, obviously hoping that keeping the boy out of the limelight will help the relationship fair better, seeing as Reynolds scampered off with Blake Lively their split, and she also dated Sean Penn, which can't have been fun.

The last time she spoke about marriage she was a bit flip and casual about the whole thing saying 'I never think about marriage. Is that weird? The only time I ever think about it is when people ask me. It's really not important to me.' Well fingers crossed this one works out for you love.
