Wet T-shirt contest! Penny Lancaster reveals her model figure in sea-soaked top as she lets loose on Hawaii holiday with husband Rod Stewart and their family

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, while also taking a dip in the sea in a white T-shirt, rendering it completely - and alluringly - transparent.

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.

The sopping wet garment did little to cover her stunning figure as she frolicked in the surf, sticking to her ample chest and revealing the colourful bikini underneath. 

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.

Hold on! The model made sure to avoid a major wardrobe malfunction as she rearranged her bikini top after slipping into the ocean

Be a beach babe in a printed bikini like Penny's

It's a testament to Penny Lancaster's outrageously youthful looks that she stood out amidst the entire Stewart clan on a recent beach break.

Let's give a little credit to the bikini though! The blonde beauty stunned in this gorgeous mixed print two-piece. We love the opulent gold chain details and clashing leopard and floral print. All encased in that universally flattering triangle shape and you've got some seriously stylish swimwear!

And for all that detail you'll be shocked to hear that it's actually from Victoria's Secret. Sadly Penny's exact pick is now sold out (boo) but you can nab a similar bikini with that delicious mixed print at the site now (click right).

The former Strictly Come Dancing contestant was also seen rearranging her bikini top, which almost billowed south once she went under.

But her tropical print bikini, which also featured a contrasting leopard print pattern, and wet T-shirt was just one of two swimwear looks Penny donned during their day at the beach.

The Essex-born beauty also rocked a simple black bikini beneath a patterned kimono.

Her blonde locks, which were partly concealed beneath her straw hat, were worn in a naturally wavy style and her eyes were shielded from the rays beneath a pair of aviator sunglasses as she cooled off in the ocean carrying her son Aiden, four. 

The mother-son duo looked the perfect family picture as the youngster, who was clad in orange board shorts, smiled and laughed whilst holding on tight to his mum as they jaunted through the rippling tide.

But Aiden and Alastair were just two of Rod's brood who joined Penny and himself on holiday.

His daughter Kimberly - who Rod shares with ex-wife Alana - took to the beach in style in a patterned tunic.

Protecting her face from the sun, the 36-year-old sported a cream sun hat and a pair of reflective circular sunglasses whilst carrying her daughter Delilah, four, who is fathered by The Usual Suspects actor Benecio del Toro, down to the beach.

Kimberly's brother Sean, 34, was likewise seen heading down to the white shores in a pair of camouflage-printed board shorts and a grey shirt, which he left unbuttoned to reveal his tattooed torso.

Rod's daughter Ruby - from his eighties romance with model Kelly Emberg - was also on the trip, with the 28-year-old mannequin showcasing her toned bikini body in a stylish two-piece which featured daring cut-out strips in the bottoms. 

At one point the blonde enjoyed a Baywatch moment as she ran across the beach, her wet locks swept back from her face, following a dip in the crystal blue waters.

Both of Rachel's children with Rod joined their father on the trip, with their son Liam, 20, frequently chatting to his father - who was clad in a blue vest top and luminous yellow shirts, along with a white straw hat - as they walked along a tree-lined path that took from their hotel down to the beach.

The handsome youngster rocked a pair of floral swim shorts for his frolic in the balmy climes and left his thick brown locks in an untamed style.  

Liam is a professional ice hockey player, who made his debut for Great Britain earlier this year.
