Blake Lively and Ryan Reynolds are reportedly expecting their second child

The couple are already parents to 16-month-old James.

Ryan Reynolds and Blake Lively are expecting their second child, according to reports.

A source close to the couple told PEOPLE magazine, 'Blake is absolutely thrilled and so is Ryan', although the pair's representatives have yet to confirm the news themselves.

Earlier this month, rumours of pregnancy began circulating after Blake was pictured wearing a wetsuit whilst reshooting scenes for her upcoming film The Shallows. The actress was spotted hiding her stomach behind a surfboard and knotting a robe around her waist to conceal any potential bump.

Ryan, 39, and Blake, 28, welcomed their first child, a daughter named James, on December 16th 2014, although they didn't confirm her date of arrival until her first birthday a year later.

Ryan celebrated the milestone by jokingly tweeting 'Happy birthday to my baby girl! Sad I lost my virginity. But thankful I have a daughter' on the anniversary of James' birth.

The notoriously private pair keep their daughter out of the public eye, having only sharing a few snaps of the tot on social media.

Blake admitted in April 2015 that becoming a mum had completely changed her perspective.

'Everything is different,' she said during an appearance on Live! With Kelly and Michael at the time. 'You see a balcony and you're like, 'Oh God, the hotel needs to demolish this balcony because my child can't go anywhere near it.' So, everything is just like, so much more heightened. We're crying all the time for no reason.'

Ryan, meanwhile, said he 'couldn't get enough' of his daughter, confessing during an interview on SiriusXM EW Radio, 'If I could have nine daughters, I would be thrilled. Really, like I genuinely would be.'

He added to PEOPLE, 'I would love to have a little boy at some point, but I would not be an unhappy man if I had a six-person soccer team of girls'.
