The pair also made an appearance at the San Diego Comic-Con in mid-July.
“They’re really cute together and seem very comfortable with one another,” the source said.
“He’s a great guy.”As Us Weekly exclusively reported, Mc Adams was linked to her True Detective costar Taylor Kitsch last summer.
Prior to that, the actress dated her Midnight in Paris costar, Michael Sheen, for three years before the pair split in 2013.
For those looking to get in on the scoop, here is a rundown of the men Mc Adams has had by her side so far: After Rachel and Taylor Kitsch’s breakup she was quickly seen together with Hollywood screenwriter Jamie Linden who is mostly famous as the writer of the 2006 film We Are Marshall.
It is fair to say that Hollywood’s leading lady has an eye for the winners.
The pair hugged and kept their arms around each other as they waited in line to enter the famous Louvre art museum. Still, the twosome's 2005 sexy smooch isn't the only time PDA has been flaunted at the MTV awards show.Nonetheless, be sure to ch-ch-check out the other moments for yourself (below)!The actress admitted that dealing with stories about her dating life is "weird." "I guess you just have to laugh at it at a certain point," she said, not exactly denying or confirming the rumors. So whether they are dating and just keeping it private or they aren’t dating at all, Mc Adams did bring up a valid point that can apply to us all. She explained that just because a man and a woman are photographed together, doesn't necessarily mean they're a couple.And that's exactly what Mc Adams did, laughing off the reports that she and Kitsch are an item. Back in June, she and Kitsch were spotted dining together at Osteria Mozza in West Hollywood, California, which further fueled the speculation that they were more than friends.Mc Adams, 37, wore a sleeveless black dress and mauve suede booties for the outing, while Linden donned a gray T-shirt and jeans for their day together.
