Rachel McAdams and Taylor Kitsch, who are starring alongside one another on the latest season of True Detective, might be dating.

Rachel McAdams, Taylor Kitsch Dating?

While filming True Detective, McAdams and Kitsch, who are both from Canada and have been “friends for years,” ended up growing “closer on set,” a source told Us Weekly.

“It hasn’t been long,” another insider told the magazine. “But it’s serious. I don’t know if it’s full-blown love yet, but they talk constantly. They’re really into each other. She talks about him all the time!”

Earlier this month, the actors were spotted out on a dinner date at Hollywood hotspot Osteria Mozza.

McAdams, who famously dated her The Notebook costar Ryan Gosling, previously said in an interview that dating a costar while filming can be distracting – but that she has dated actors after filming wraps.

“A set may seem like a good place for romance, but I don’t think it’s very conducive; it’s too distracting,” McAdams told Glamour. “Every relationship I’ve had with a coworker comes after the fact.”

Neither Kitsch nor McAdams have commented on the rumors.
