While promoting his new film, Concrete Cowboy, at the Toronto International Film Festival on Sunday, actor Idris Elba let slip to ET Canada that he and wife Sabrina Dhowre are now parents to a baby boy. "So, it really resonates with me, I'm a father of two boys, and definitely I can't wait for my youngest to see this film," Idris said as he discussed the importance of the film. The Thor actor didn't reveal the little one's name, but he is father to 18-year-old daughter Isan and 6-year-old son Winston. Fans reacted with shock and surprise with the news that Elba is now a father of three. "Congratulations Idris," one tweet read. "My baby daddy just had another baby! Love you Idris," another over enthusiastic tweet wrote. "Another mini Idris! 2020 ain't so bad!" another message read.

Idris and Sabrina met in Canada, where the former Miss Vancouver is from.

They began dating on the set of the 2017 film, The Mountain Between Us.

Speaking about the early days of their relationship, Idris told Vogue: "Falling in love while making a movie about falling in love is pretty special."

"You know, I’m 47 this year, been married and lived a full life before I even met Sabrina," he continued. "It wasn’t something that I wanted to do, get married again."

The couple made their debut walking the red carpet at the 2017 Toronto International Film Festival for the screening of the Elba's film Molly's Game.

He said: "I think it’s an interesting space, especially for her. She’d never done a red carpet before and I tend not to do that. It was nice actually."
