FormerOne Tree Hillstar Chad Michael Murray has welcomed his second child into the world with wife Sarah Roemer, announcing the news on Instagram overnight.

Alongside an image of his newborn baby girls’s hand holding his own, 35-year-old Murray wrote that he is a very “lucky guy”.

“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.”

It is a second child for the Hollywood couple, who welcomed a son into the world in November 2015.

The notoriously private high-profile duo are yet to publicly announce the name of their first-born, meaning it may be a long while before we know the name of the newest addition to their family.

It’s not the only detail of their private lives the couple have been coy about, either. News of their second pregnancy only broke back in November, and news outlets are yet to pinpoint exactly when the couple married. It’s believe they held a secret ceremony sometime in late 2014 or early 2015.
