Posing with a drink in hand, Simone looked happy and confident has she flashed a glimpse of sideboob in her skimpy swimwear.

The former Playboy model also flaunted her pert derrière in a pair of tie-side bottoms and accessorised with a leopard print shawl.

She styled her long blonde hair in beachy waves and glanced playfully at the camera behind a pair of dark sunglasses.

Always glamorous! It seemed unlikely the model was heading for a dip in the pool any time soon as she appeared to be wearing a full face of makeup
