New couple alert! Sebastian Stan and Margarita Levieva are dating, multiple sources tell Us Weekly.

"They've been friends for awhile," a source tells Us of the Captain America: The Winter Soldier actor and the Revenge alum. "They're having fun together and seeing where it goes," the insider adds. "They're both very art-minded and thoughtful people."

Indeed, the couple—who both starred in Ashton Kutcher's 2009 flick Spread—are having fun. Another source tells Us the new couple "didn't leave each other's side" while at Taylor Schilling's 30th birthday party at NYC hotspot Catch Roof on Saturday, July 26.

"They were with Joshua Jackson all night long," the eyewitness adds of Stan and Levieva, who "spent the entire night hanging out together on the terrace."

Stan, who was previously linked to Gossip Girl star Leighton Meester and Jennifer Morrison, posted a discreet picture of the Revenge alum two months ago on his Instagram and another of her walking in the rain on July 5 with the caption: "I mean... #yes."
