Instagram boyfriend! Kaia Gerber’s beau Austin Butler takes sizzling bikini-clad snaps of the supermodel before pair pack on the PDA during Mexico break

Kaia Gerber’s boyfriend Austin Butler served as the ultimate Instagram boyfriend as he shot sizzling snaps of his bikini-clad girlfriend in the pool on New Year’s Day.

The 21-year-old posed up a storm in her sexy swimsuit as her boyfriend took photos of her during her getaway to Cabo San Lucas with her family.

During breaks from their photo shoot, Kaia and Austin, 31, were the epitome of couple goals as they packed on the PDA in the pool.

Kaia clung to her beau as he leaned down to press his lips against hers beneath the sunshine.

The statuesque stunner looked sensational in a bronze bikini top paired with taupe bottoms as she soaked up the sun with shades concealing her eyes.

During her shoot with Austin, she looked phenomenal putting her bikini body on display whilst posing languidly in the water.

Austin threw himself into the role of photographer, crouching down low to the floor to capture his girlfriend in the very best light.

But Kaia made his job easy as she served an array of perfect poses.

Once she was out of the pool, Kaia displayed her stunning physique as she wandered out into the sunshine.

The beauty, who is the daughter of modeling icon Cindy Crawford, beamed with happiness as she wandered along the pool deck.

As Kaia walked around the deck, her boyfriend cooled down in the pool.

The Elvis star was the epitome of relaxation as he lounged in the water wearing his sunglasses.

The Carrie Diaries actor also sent temperatures soaring as he emerged from the water with his muscles on full display.

Kaia and her beau have been enjoying a holiday in Cabo San Lucas, Mexico with Kaia’s parents, Cindy Crawford and Rande Gerber, her brother Presley and his girlfriend.
