The Big Bang Theory star Johnny Galecki has sold a new sitcom to Fox.

According to Deadline, Galecki is working with Family Guy writer Ricky Blitt and producer Stephen McPherson on the comedy, which will be called Here's Your Damn Family.

The comedy will follow a 30-year-old man still living with his mother who finds his life shaken up when she gets married and her new husband moves in, with his three children.

Galecki - best known for playing Leonard on The Big Bang Theory and previously for his role in Roseanne - will also produce the new sitcom.

His Theory co-star Jim Parsons (who plays Sheldon) is also developing a new TV show called Prodigies, which is about child geniuses.
