They've been keeping things completely under-the-radar, but things are continuing to heat up for former True Detective co-stars Rachel McAdams and Taylor Kitsch. 

The couple, who met while filming the HBO anthology series, have reportedly been dating since last summer. Now, according to Life and Style, they're at a more serious point in their romance that includes virtual cohabitation.  

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

The two, who have kept a largely low profile, allegedly enjoy spending time together by going for brunch and heading to the gym together, and McAdams even loves cooking for her man.  

Things have even reportedly gotten serious enough that Kitsch, 34, has met McAdams' family, and the 37-year-old's relatives hit it off with the actor.  

"He immediately bonded with Rachel's mom, Sandra, which made Rachel really happy," the source said.  

The report comes after the two kept such a low profile that it was rumored not long after they began dating that they had split up, with McAdams saying last August that she was single, and revealing the things she was looking for in a guy. 

"There are three cardinal points: kindness, humor sense and flexibility," she said at the time. "Apart from a taste for adventure, I'm content with that." 

McAdams has kept a low profile when it comes to her relationships through the years. While she and former The Notebook co-star Ryan Gosling were given a lot of attention during their romance, she has since dated Michael Sheen, Josh Lucas and Patrick Sambrooke to far less fanfare. She also reportedly briefly dated her Southpaw co-star Jake Gyllenhaal, though that was never confirmed.  

Kitsch was rumored to have hooked up with his Friday Night Lights co-star Minka Kelly, and was linked to model Jessica White from 2006-2007.  

McAdams also neglected to bring Kitsch with her to events this past awards season. She was present at nearly all the major awards shows because of her nomination for Spotlight, but her date was most often the journalist she portrayed in the film, Sacha Pfeiffer.
