Penny Lancaster puts on a glamorous display in plunging kaftan while paddling with son Aiden, four... before taking a dip in a bikini and T-shirt
She's famed for her career as a lingerie model.
And Penny Lancaster proved her assets are still as ample as ever whilst spending a day at the beach with her husband Rod Stewart and their sizeable brood in Maui, Hawaii, on Saturday.
The 44-year-old star sported an array of beachwear as she soaked up the rays with her family on the tropical island.

Playing around in the ocean with her son Aiden, four, the model-turned-photographer looked like the entrant of a wet T-shirt competition as she layered a colourful printed bikini beneath a simple white tee which got completely drenched whilst she splashed in the sea with her son.
Penny was attempting to help both Aiden and son Alastair, ten, body board, though her efforts soon saw her descend beneath the waves, drenching her previously preened blonde locks.
Nevertheless, her little ones looked to be having a great time as they entertained themselves on their boards, as did the former face of lingerie brand Ultimo who emerged from the water laughing after her wet ordeal, her sodden straw hat limping in her hand.
