Scarlett Johansson appears to be really into her new boyfriend.

The He's Just Not That Into You star was spotted this week strolling through NYC with her boyfriend Romain Dauriac. On Scarlett's ring finger? A colossal diamond ring. Hmmm...

The pear-cut diamond ring on her finger is sparking rumors that Scarlett and her French boyfriend of three months might already be engaged, according to the Daily Mail.

The couple started dating in November after meeting through mutual friends. Romain is 30 years old and works in the magazine business.

This wouldn't be ScarJo's first foray into marriage, as she finalized her divorce from first husband Ryan Reynolds in July 2011. 

Since her divorce, Scarlett was linked to Sean Penn for a bit, while her ex Ryan is now married to Blake Lively. 

We'll have to wait and see if Scarlett's bond to Romain is about to become ironclad. (Get it — "ironclad"? Because she's in the Iron Man movies?)

UPDATE: Scarlett's rep told Gossip Cop she is NOT engaged. But maybe the rep meant "not engaged yet"?
