This Hollywood actor is a dad for the first time!

And now for some seriously good news: Joseph Gordon-Levitt has become a father for the first time… and we're so happy for him!

Yes, the 500 Days Of Summer actor and his wife, Tasha McCauley, welcomed a baby boy last weekend. 

The duo married in a secret ceremony at the end of last year – so it's no surprise that they kept Tasha's pregnancy fairly quiet too. 

A source has now confirmed to Us Weekly that "everyone's happy and healthy" although unsurprisingly, the couple has yet to reveal their baby's name.

Ms McCauley, 34, is a technology entrepreneur and the CEO of robotics company, Fellow Robots. She is rarely seen in public with her Hollywood star husband of eight months.

Joseph, also 34, has explained in the past that his spouse simply prefers to stay out of the limelight. 

"I have a girlfriend but I tend not to really like to talk about it in public," he said in September 2013 shortly after they met through mutual friends and began dating. 

"The girl that I'm with, she really doesn't want to be a part of that," he added.

Boasting a career which spans almost 25 years, former child-star JGL is probably best-known for his roles in Inception and The Dark Knight Rises.
