The 35-year-old actor and wife Sarah Roemer have welcomed a daughter into the world, a sister for their 21-month-old son, whose name they have never disclosed publicly.

Chad shared a picture of his new baby holding on to his finger and added the caption: "Don't worry little girl you can hold on as tight as you want for as long as you want, I'm already yours & I'll never let go.

"I've now two incredible women in my life. My son & I are two lucky guys.(sic)"

The former 'One Tree Hill' star confirmed he and his 32-year-old spouse were expecting another baby last November when he shared an image of himself sucking a pacifier on Instagram.

He captioned the post: "Is it a Rave or Daddy Duty ... #daddyduty #Thispacifiermakesmereadyforfootballsunday. (sic)"

And in January, the couple confirmed they were expecting a baby girl in a picture taken at the premiere of 'John Wick: Chapter Two'.

Sarah captioned her social media post: "We're fans. It was great! Baby girl could have used some earmuffs though... #johnwick2 #datenight (sic)"

The pair - who got married in 2015 following just months of dating - are keen to keep their private life tightly under wraps.

Chad said recently: "I'm really good at staying under the radar these days. My wife and I, we don't go to the quote-unquote 'cool' places. We have our own life, we have our dogs, we have our lifestyle that we truly enjoy, and we've got a cabin if we want to get away and go camping. I feel very good about my private scene. I'm going to do everything I can to protect my family."

And, although he's only been a father for less than two years, the 'A Cinderella Story' hunk is determined to raise his children so they understand the meaning of "respect" and to be very sporty.

He explained when asked what type of father he is: "Ooh, that's tough. I'm a respect first kind of guy, so I think certain things that I want my son to have is just respect and just to be a kind human being. I'm a big sports guy, an outdoorsy guy, so I'll be having him fishing at five or six..to take him kayaking and hiking."
