Heidi wore her platinum blonde locks in a loose braid and accentuated her cosmetically-enhanced features with natural make-up. 

Spencer kept things casual for his vacation look, going shirtless in patterned board shorts, flip flops and a sideways cap. 

Looking more in love than ever, the couple fed each other ice cones as they soaked up the Hawaiian sunshine.

Evidently enjoying her pregnancy, Heidi has been posting a series of snaps of her baby bump as she makes the most of her last vacation before welcoming her little bundle of joy. 

Heidi and Spencer announced they were expecting their first child in April, before confirming they were having a boy one month later. 

'It was in my heart to have a boy', Heidi told US Weekly magazine. 'I thought Spencer really used to want a boy, and then a few months ago we had a conversation where he said, “Let’s just make sure it’s healthy. Boy or girl, I don’t care".

'I hope to have a little girl one day, but for my first child, I really wanted a son.

'I’m hoping to God that we don’t just have one, but if we do, I wanted a son. I thought it’d be a more natural bond for Spencer since he and his dad are so close.' 

But Heidi admitted she was struggling to come up with a suitable name for their little bundle of joy. 

'We’re having a seriously challenging time,' she told Refinery 29. 'A lot of the names I like are taken.' 

Heidi has been paying close attention to her weight and nutrition during her pregnancy. 

Last month, she took her Snapchat followers on a visit to the doctor's office, where she said that she's 'already gained 25 pounds' and is expected to pack on about 15 more.

She joked: 'I think I over ate.'

Heidi and Pratt, who have been married more than eight years, have been given an October 19 due date. 

Heidi has been pregnant at the same time as her former The Hills co-stars Lauren Conrad, 31, and Whitney Port, 32.

Lauren and lawyer husband William Tell welcomed baby son Liam on July 5, while Whitney and her husband, The City producer Tim Rosenman, announced the birth of son Sonny on July 27.
