The 'Deadpool 2' star turned 42 on Tuesday (23.10.18) and followed his tradition of taking to social media to make a joke on his special day, this time quipping about his father referring to his birth as the time "the condom broke".

Alongside a sweet throwback picture of the pair at one of Ryan's birthday parties as a child, the Canadian hunk wrote: "Happy Birthday to me. Or as Dad used to affectionately say, "the condom broke". (sic)"

Last year, the 'Proposal' star - who has daughters James, three, and Ines, two, with wife Blake Lively - joked about starting "a new life" without his family.

The actor's little girls were excited to surprise him on his special day, and he joked that he "snuck out" of the house.

Taking to Twitter, he teased: "My kids tried to surprise me for my birthday this morning. I totally heard them coming and snuck out to start a new life somewhere else."

In reality, Ryan has a lot of love for his family, and previously said he would be "thrilled" to add more females to his brood in the future.

He said: "If I could have nine daughters I would be thrilled. Really, like I genuinely would be.

"There's more love, there's more diapers. There's more all that stuff, you know? [Fatherhood] is the best thing. It's the best thing that could ever happen to you."

And Ryan has previously revealed how grateful he is that his job is so flexible it allows him to fit it in with family life.

He said: "I don't take a second of it for granted. I'm also really lucky: my work is intense for periods, but then I can also take time off, and a lot of people can't. So I'm grateful for that. I love watching my kids grow and evolve, and I hope that I get to do that for a huge amount of their lives. Until they kick me out."

However, the 'X-Men Origins: Wolverine' actor previously admitted parenting has given him "anxiety".

He said: "I think you're just more desperate in everything you do cause you're like, 'I've got 10 minutes to do this, and then I gotta get home for a thing, and a thing, and a thing.' There's just no time anymore, so you're hardened by it. Anxiety, I think, that's probably it."
