While McAdams is extremely private, she was spotted holding hands with screenwriter Jamie Linden in the summer of 2016, sparking rumors that the two were a couple. E! shares that the two were also photographed together attending a friend's wedding in Virginia, though they have never walked a red carpet with one another.
Though McAdams is starring in the upcoming film Game Night, she did not attend Wednesday's premiere and has kept a low profile in recent months. She was last photographed in a baggy jacket at an airport in Toronto.
McAdams has not yet commented on her speculated pregnancy.
Back in 2009, the actress told PEOPLE she would love to have children.
"Having a few [kids] would be great," she said, adding that she's "looking forward to it someday."
McAdams also praised her own mother's influence.
"My mom is a great inspiration to me," she said. "She's a nurse and very nurturing and gentle. She lets me be who I am. Hopefully I can take on those qualities and be as great as her."
