It appears the romance that was allegedly sparked on the set of True Detective last year fizzled out quietly and that Rachel McAdams already moved on from Taylor Kitsch with a new man.

Rumors first circulated last July that McAdams and Kitsch were dating after growing closer on the set of the show, but the pair kept quiet about the romance, with McAdams even claiming she was single in an interview one month later.

However, in March of this year, the two were once again rumored to still be together and even taking their relationship to the next level by moving in together.

"They're practically living together," sources said at the time. "Rachel is at Taylor's condo all the time."

The two were reportedly keeping a low profile to keep their relationship low-key, with dates often consisting of going to the gym or out for brunch, or even staying in with McAdams cooking, The two also reportedly introduced one another to their families.

However, it appears something changed along the way, as McAdams and Jamie Linden were first spotted together while attending a wedding together in June, and they have now been spotted together again while running errands in West Hollywood over the weekend, specifically to buy home furnishings, sparking rumors that things were also seriously heating up between them as well.

According to The Daily Mail, the two purchased bed pillows, and were seen appearing to test mattresses at a store as well.

Linden is best known for writing the screenplays and co-producing the films We Are Marshall and Dear John, as well as directing the film 10 Years.

McAdams shot to stardom and became a household name after turns in The Hot Chick, and most notably, both The Notebook and Mean Girls in 2004. She famously dated her Notebook co-star Ryan Gosling for four years until they broke up in 2008. Since then she's also been linked to actors Josh Lucas and Michael Sheen, and music manager Patrick Sambrook.
