Rachel McAdams might‘ve found love with another gorgeous co-star.

Us Weekly is reporting that McAdams is dating Taylor Kitsch, who co-stars with her in HBO’s crime drama “True Detective.” The two were spotted dining together earlier this month at Osteria Mozza in West Hollywood.

“It hasn’t been long,” a source supposedly told Us. “But it’s serious.”

No other outlets have reported on the relationship and reps for both were not immediately available to comment.

If the rumor is true, however, it wouldn’t be the first time romance has sparked on set for McAdams. The 36-year-old beauty dated Ryan Gosling after meeting on the set of 2004’s “The Notebook” and Michael Sheen after meeting while filming 2011’s “Midnight In Paris.” In April, rumors swirled that she was dating Jake Gyllenhaal, her “Southpaw” co-star, according to People magazine.

“I usually take away one close relationship from every job, some romantic, some not,” she told InStyle in 2010.
