Congratulations are in order, as Rachel McAdams and her screenwriter boyfriend, Jamie Linden, have reportedly welcomed their first child together.
According to Hollywood Pipeline, the couple - who were first photographed together in April 2016 - have been spotted out and about with their newborn son.
Rumours shrouding the actress’ pregnancy first broke back in February and the 39-year-old has kept a low profile ever since, even skipping the red carpet premiere of her latest film Game Night.
In 2009, McAdams hinted at her desire to become a mother in an interview with People magazine: 'Having a few [kids] would be great, I’m looking forward to it someday.'
She continued, 'My mum is a great inspiration to me. 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.'
The following year, she told InStyle, 'Part of me is very attached to the idea of having children. It’ll depend on if I find the person I want to do that with.'
The Canadian actress previously dated fellow Notebook co-star, Ryan Gosling, from 2003 to 2007. Three years later, she moved on with Michael Sheen after meeting him on the set of Midnight in Paris.
McAdams reportedly met her current boyfriend, Jamie Linden, back in 2006. The couple have yet to comment on their exciting news.
