ScarJo not Engaged? Big ring on finger, but Johannson says no marriage vows for 'Cat on a Hot Tin Roof' star.

Scarlett Johannson is claiming she is still a single lady. Just one that sports big diamond rings while holding hands with her man.

The 28-year-old actress was spotted walking around New York City recently with boyfriend Romain Dauriac, a French journalist. Displaying a pear-cut diamond, the 'Cat on a Hot Tin Roof' star is still no hurry to walk the aisle. Last November, Johansson and Dauriac publicly came out as a couple, just a few weeks after ScarJo broke up with ad executive boyfriend Nate Naylor. The Frenchman attended Johannson's premiere in New York for her movie "Hitchcock" with the actress on November 18th. She was previously married to actor Ryan Reynolds, who filed for divorce in 2010 and has since married another blonde actress, Blake Lively.

Johansson was spotted with Dauriac sporting a black coat and black jeans at an ATM and picking up some coffee before they headed to an East Village tattoo parlor. In a February interview with Elle UK, Johnasson insisted that she is no hurry to get back down the aisle.

"I never think about marriage. Is that weird?" she told the magazine. 

"I got married when I was young and it was incredibly romantic and I liked being married, actually," Johansson told ELLE UK.

"But it is different. It's hard to put into words. To me, being in a functioning relationship doesn't mean you have to be married. It's really not important to me. I'm not having kids any time soon, I'm in a nice relationship, I'm working a lot."

Johannson may want to call up singer Katy Perry on how to deal with gossip hunters after her ring-wearing motives. The 28-year-old was photographed last week with a large hear-shaped ruby ring on a finger that had many speculating that she and boyfriend John Mayer had tied the knot. Perry has not confirmed that she and Mayer are engaged.
