She flew out to Barbados with boyfriend Simon Cowell and their son Eric earlier this week for a spot of winter sun.
And Lauren Silverman looked like she was getting into the holiday swing of things as she stepped out on the beach in a striking little black bikini on Wednesday.
The 37-year-old American looked stunning in her two-piece as she walked about the beach and stepped into the sea, her little boy firmly in her arms.
The beautiful brunette, who gave birth to Eric in February this year, cut an effortless figure in the idyllic location.
She finished her beach-ready look with a stylish yet simple trilby hat, her long locks tied up in a utilitarian style, and a pair of colourful, reflective sunglasses.
She showed off her seemingly endless pins thanks to the high-cut swimwear bottoms, while carrying her tot on her hip.
Double-act: Lauren kept hold of her adorable tot, who looked sweet in a bucket hat and checked shorts
Itsy-bitsy bikini: The 37-year-old mum wowed as she stepped into the bright clue surf
Cuddle time: Eric looked snug as his doting mother kept hold of him throughout their beach excursion
Baby's first dip? Although he's been to Barbados before - a favoured location of his parents - Eric looked amazed at the sea below him
Beach babe: Lauren certainly looked striking in her tiny black bikini, revealing her fantastic post-baby body
The 10-month-old was well and truly covered up protectively from the sun's rays: he looked adorable in a bucket hat, t-shirt and printed shorts.
Lauren was totally enamoured with their son, who remained in her arms throughout their beach excursion.
The slim and shapely star appeared relaxed, no doubt thanks to their sun-soaked getaway after the busy past few months for her music mogul boyfriend, who has been filming the latest series of X Factor in the UK.
Later on, Simon joined her on the beach with their cute Yorkshire Terrier pooches Squiddly and Diddly - and a third pup - for a saunter up the sand.
Time for a cuppa? A friend of Simon's girlfriend appeared in the shallow water, apparently holding up a cup filled with a beverage
Stylish as ever: Although on the beach, Lauren managed to look as well-dressed as normal, rocking a trilby hat and reflective sunglasses
Leggy lady: She showed off her seemingly endless pins as she strutted up the golden sand
Flawless: The American socialite looked as beautiful as ever in her string bikini
The devil's in the details: She clearly wasn't going for a full swim, as Lauren continued to wear her large gold watch on her wrist
Lauren covered up with a casual white shirt layered over her skimpy swimwear, but her ample cleavage remained on full show thanks to her choice of buttoning the garment just once over her waist.
She also changed her hair, opting for a slightly messy beach-perfect plait worn down one side.
And Simon matched his stunning lady, wearing a pair of bright white knee-length beach shorts, and going topless.
The 55-year-old smiled as he walked his pooches, but he appeared to have caught the sun a fair bit in his couple of days in Barbados, with his shoulders glowing a sore-looking shade of red.
Loved-up: Simon Cowell later joined Lauren on the beach with their cute Yorkshire Terriers Squiddly and Diddly, and a third mystery pup
Happy families: The couple appeared to be struggling from their overzealous little dogs, who were trying to go elsewhere on the beach
Caught the sun? Simon appeared to be sporting quite the sunburn on his shoulders, but he didn't seem bothered
Sexy cover-up: Lauren worked a stylish, casual white shirt worn over her bikini, looking as gorgeous as before
Carry me! One of the pair's little dogs eventually relented, and was carried across the beach by a smiling Lauren
The loved-up couple, who have been an item since 2013, couldn't hide their smiles as they enjoyed another chilled out day in their favourite location.
The three had flown out to the Caribbean island earlier in the week, just after Simon's act Ben Haenow was revealed as the winner of the latest series of the ITV talent show.
And on Tuesday, Simon and Lauren let their metaphorical hair down as they shared several public displays of affection on the beach.
So they were clearly ready for a well-earned break, especially after their first year together as new parents.
Lauren already has a child from her previous marriage to businessman Andrew Silverman, nine-year-old son, Adam.
Behave! The dogs appeared to be finding the whole experience quite exciting
Chest hair, don't care: Simon proudly showed off his own beach body as he went topless
Friendly: Simon and Lauren stopped to let fellow beach-goers play with their dogs
Meanwhile, Eric is Simon's first child, and becoming a father has clearly been a wonderful experience for him.
Earlier this year, shortly after the birth of his mini-me, he told Extra: 'I was born to be a dad.'
And he was concerned that he may like his pets more than his little boy, but that wasn't the case.
'I actually said to Lauren beforehand, 'What if I like the dogs more than him?' and she said, 'You're gonna be absolutely fine,' and then literally within seconds of him being born, I got it,' he added.
Soaking up the sun: The girlfriend of Simon Cowell appeared totally relaxed on the Barbados beach
Back again! Simon and his girlfriend Lauren had returned to their favourite holiday hotspot - they often venture over to the Caribbean island for vacation
Later in the day, they were joined by Simon's ex-girlfriend Sinitta and her current beau Jason Gale.
Simon walked hand-in-hand with Lauren and his former flame, as the singer's lofty man followed behind them.
And the three-fun-loving stars opted to take rides out across the waves on jet-skis, with Sinitta showing off her prowess by standing up on her water vehicle proudly, her large visor pushed up off her face.
Stunning: Lauren, 37, wowed in her little black bikini and casual undone white shirt, revealing her ample cleavage
Friends! Sinitta, Lauren Silverman and Simon Cowell looked as close as ever as they enjoyed their Barbados holiday while holding hands, as Sinitta's boyfriend Jason Gale walked behind them on Wednesday
Getting active: Sinitta hopped on board a jet-ski, showing off her amazing legs while scooting across the ocean
My turn! Lauren also got on a jet-ski, wearing a sensible life jacket along with her black cap and sunglasses
Pro: Simon is often seen on jet-skis, and he certainly looked comfortable on the water vehicle
Loved-up: The two - who have been an item for over a year - couldn't help themselves from public displays of affection while on the surf on Tuesday
