On Wednesday night, McAdams noticeably skipped the premiere of her new comedy film "Game Night", for which she is receiving rave reviews, while other cast members, including Jason Bateman, walked the red carpet. News she's been keeping a low profile because she is preparing to become a mum.
She's typically very low-key when it comes to her private life being public, but her partner is believed to be screenwriter Jamie Linden, who's penned scripts like Money Monster and Dear John.
However, in a recent chat with Parade.com, she revealed she had "so much" to look forward to in 2018.
Rachel McAdams is going to be a mum!
"I love the beginning of the year", she gushed.
Noted as being one of her longer serious relationships, McAdams didn't keep her three-year relationship with Welsh actor Michael Sheen a secret at all. "So I think it'll depend on if I find the person I want to do that with", she told InStyle in 2010. She's a nurse and very nurturing and gentle.
'My mom is a great inspiration to me...
Following the success of The Notebook, fans got their wish when we saw McAdams and her hottie co-star Gosling hook up in real life.
Meanwhile, Linden's exes include actress Zooey Deschanel, who he dated for two years until their split in 2014.
