Sam Worthington and girlfriend, Lara Bingle, have welcomed their first child together.

The 38-year-old Avatar actor and his rumored Australian wife, Lara Bingle, gave birth to their first son together.

E! News confirmed that the 27-year-old gave birth a few days ago, but the couple has yet to release the birth date or their newborn's name.

Worthington and Bingle have kept many details about the pregnancy hush-hush. The blonde model debuted her baby bump back in January and Australia's OK! published the photos.

The photos featured the model wearing a plain white t-shirt, hugging her big belly, while out with her mother in Palm Springs, Calif. The photos were on the cover of that week's Ok! magazine.

Prior to the photo debut, E! News reported that the couple had done baby shopping at Bel Bambini, a high-end baby boutique in West Hollywood. Eyewitness reports informed the entertainment site that the couple was looking for nursery furniture.

Reports about the couple's pregnancy began in September 2014.

However, this was not the couple's first secret. The two had kept their marriage a secret until earlier this month. Bingle had changed her Instagram name to "Lara Bingle Worthington."

The couple had first publicly announced their romance back in October 2013 when they were spotted kissing in Sydney, Australia. The two were introduced by Natalie Imbruglia, a mutual friend.
