Lara Bingle has been papped in American sporting what appears to be a well-developed baby bump.

Australian magazines, OK! and Woman's Day, have both released pictures of the 27-year-old in Palm Springs.

The model's mother, Sharon, was also there when Bingle, who OK! claims is already six months pregnant, was snapped in comfy casual clothes, and a floppy hat.

Her baggy white T-shirt is visibly fitted around her burgeoning middle.

Bingle and partner Sam Worthington, who have been the subject of pregnancy rumours since mid last year, are yet to comment on the pictures.

Speculation about a mini Bingle-Worthington was recently reignited by fans when Bingle posted buxom underwater pics on Instagram.

OK! claims a friend told the magazine the couple were excited about the baby and Bingle was having an easy and healthy pregnancy.

"Sam and Lara are going to amazing parents," the source told the magazine.

"He's always wanted to be a dad one day."

The couple are notoriously private and reportedly wed in a secret ceremony last year.
