Joseph Gordon-Levitt welcomes baby number two with wife Tasha McCauley

Actor Joseph Gordon-Levitt has welcomed his second son with wife of three years, Tasha McCauley.

The couple are already parents to another one-year old son, but Joseph, best known for his roles in 10 Things I Hate About You, Inception and 3rd Rock from the Sun, and his software developer wife Tasha, are notoriously private about their personal lives.

They were married in a private ceremony in 2014, and welcomed their first son a year later, although, just like their new arrival, we're yet to learn his name or see any pictures of him on social media.

Pregnancy rumours surrounding the couple began back in May this year, when the couple were spotted out strolling together in Beverly Hills. Wearing a summer black and white polka-dot dress, Tasha was sporting what was undeniably a baby bump and resting her arm lovingly over her stomach.

It wasn't until a week later that the couple confirmed the happy news via their rep, who revealed that they were expecting their second child.

It was through their rep that Joseph and Tasha announced that their second son arrived in June, bringing the family member count up to four - cute!

Shortly after becoming a father for the first time, Joseph told American chat show Live! With Kelly and Michael hosts that preserving his son's privacy was a decision he was keen to make.

'Being in the public eye is a great thing,' he said during the interview. 'It allows me to do what I love to do, which is act in movies, but it's a choice that I made.

'My son, he's just a baby, you know? He hasn't made the choice to be in the public eye, and that's a choice that I would like him to be able to make when he's older, when he can think about these kinds of things and make that decision for himself.

.And so, for now, I'm just a protective dad, and I want to protect his privacy.'
