In one image, Iggy is seen laying on her side as she showcases her toned body whilst perching on a sun bed.

She wore her long, glossy locks in two braids for her fun under the sun. 

Squinting from the glare as she flashed a toothy grin, the blonde beauty captioned the shot: 'And I could use some sunglasses. It's sunny as s***.'

Iggy previously opened up about going under the knife for her breast augmentation to Vogue in March 2015.

'Four months ago, I got bigger boobs! I'd thought about it my entire life,' she said, before adding she initially didn't want to tell anyone but decided 'I wasn't into secret keeping.'

'I love them so much I had to talk about them,' she told E! Online a week later, adding with a laugh: 'Everybody did say, "I don't think you need to say it because no one will ever know because they're so small.'" 

Iggy has been engaged to NBA player Nick Young, 30, since June 2015.
