"They've been dating for five months," a source told People as photos emerged of the couple taking a romantic stroll in New York City. At a diner last weekend, "They were very comfortable and happy together while eating," an eyewitness tells Life & Style. "They were definitely acting like boyfriend and girlfriend. It was all very natural, Scarlett and Nate couldn't stop smiling."
After splitting from hubby Ryan Reynolds, the 27-year-old actress briefly dated much-older actor Sean Penn. But the star couple never looked as cozy together as Scarlett does with Nate. A source told RadarOnline.com: "They're keeping it very, very low key. He's not one for the limelight and fame and she likes that about him."
