Makeup free Lara Bingle steps out in a baggy jacket amid rumours she's five months pregnant as she spends a day out with Sam Worthington, son Rocket Zot and mother Sharon

Rumours began to circulate earlier this month that model Lara Worthington (nee Bingle) is five-months pregnant with her second child.

And on Sunday, the Australian model chose to cover up her figure as she joined her movie star husband Sam Worthington, their son Rocket Zot and Lara’s mother Sharon for a walk around New York City.

In an off-duty look, the 28-year-old donned a loose-fitting zip-up jacket paired with yoga trousers as she walked around the leafy suburb with her small family in tow.

Recently, The Daily Telegraph reported that Lara was five-months pregnant with her second child.

The publication claimed the former bikini model is slowly telling family and friends news that she and her husband Sam Worthington are expecting a sibling for their first-born, Rocket Zot, 14 months.

Last week, Lara opened up about the possibility of expanding her brood during an appearance on Today Extra, saying: ‘I would love to have more children, definitely.’

Speaking about Rocket's speedy development in terms of talking, she added: ‘He does a little bit but you can't really make out it, but he walked very early at 10-months so he's almost running now.

'He's an Aries baby so he's quite strong so when he doesn't want to eat something he doesn't want to eat it.'
