Multiple sources revealed the happy family news about the Oscar nominee.
McAdams, 39, has been keeping a low profile of late and was last photographed at an airport in Toronto wearing a baggy jacket.
The actress is not one to talk about her personal life often but the news site reports she was spotted holding hands with her screenwriter beau back in 2016, hence the hint that the two were a couple.
In the past, McAdams revealed that while being a mother was something she’d thought about often, she wanted to make sure she found the right partner first.
“Part of me is very attached to the idea of having children,” McAdams told InStyle in 2010, adding, “It’ll depend on if I find the person I want to do that with.”
Fair enough! Stay tuned to hear her baby announcement!
