'Fittings,' Lara captioned the throwback snap, alongside the hash-tag #7yearsago.

The photo saw the budding entrepreneur and model flaunt her petite frame in a bodycon pastel pink dress that accentuated her slim waist and delicate decolletage with cleverly placed detailing. 

Wearing just a minimal amount of makeup, Lara looked almost identical as she does now, proving that she is showing no signs of ageing despite being a busy working mother.

 The throwback snap comes just after the popular personality admitted that the thought of giving birth again is 'scary'.

'Knowing you have to give birth and there is no other way you can go is scary,' she confessed to blog Tomboy Beauty, via The Daily Telegraph.

Lara explained that once you're pregnant 'there's no going back,' but admitted it's a difficult concept to explain to people without children.

While the former swimsuit model has kept quiet about her pregnancy to the media, Who magazine reports that she's been telling friends she's expecting a boy.

'She was quite open, saying how happy she is,' a source told the magazine.

In July, Lara praised her actor husband Sam in an interview with InStyle magazine.

'He's a hands-on dad,' she said.

She added: 'He's not one to sleep through the night and not help'.

While many A-list couples choose to hire outside help when raising their children, Lara and Sam, 40, have decided against it.

'Sam and I weren't brought up with any help... It's definitely a lot harder than I thought,' she said.
