Heidi Klum looked nothing short of sensational on Sunday as she stripped down to a skimpy pink bikini while soaking up the sun in Sardinia.
The model, 50, was joined by rocker husband Tom Kaulitz, 33, as they packed on the PDA while enjoying a day out on the beaches of Cala Volpe bay.
Heidi ensured she turned heads as she slipped her toned physique in a skimpy pink two-piece with white crochet embroidery around the edge.
The German stunner added dark sunglasses and a beige sports cap at some point, while her blonde locks were left to cascade over her shoulders.
Tokio Hotel musician Tom meanwhile displayed his muscular figure in burgundy and white patterned trunks, while adding black sunglasses to his look.

The couple could barely keep their hands off each other as they frolicked together in the sea.
They then headed to the sun loungers where they canoodled some more while chilling out together.
Heidi certainly looked on great form as she flaunted her figure while stretching out on the lounger to top up her tan.
At one point, she slipped off her bikini top to ensure she wouldn’t get any unsightly tan lines on her back.
Heidi has been giving fans an insight into their lavish Italian getaway as she has been posting a whole host of sun-kissed snaps to her Instagram.
On Wednesday, Heidi looked incredible in a fashionable co-ord set as she enjoyed a fun-filled day out on a boat.
The Sports Illustrated Swimsuit star showed off her toned abs as she looked as stylish as ever in a Mona Lisa print Jean Paul Gaultier dress.
She accessorized her chic outfit with a gold belly chain and wore her tresses cascading down in waves.

Along with several stylish snaps, she also shared two videos of herself enjoying a boat ride.
Heidi recently marked her milestone 50th birthday and told how she still feels like she is 25 years old.
She admitted that she feels half her age and has ‘more energy’ than her husband, who is 17 years her junior.
She told Entertainment Tonight: ‘To be honest, I don’t let this number change my path or what I do.
‘It is, for me, just a number, you know? Because I don’t feel 50, internally. I mean, sometimes I look in the mirror and I’m like, “Oh yeah, I am 50.”

‘But internally, I feel like I’m 25. I’m full of energy. My husband is 33 and I know I have more energy than him!’
‘So, I feel like, you know, so far so good… the birthday doesn’t change anything for me. My passions are the same passions – I love to travel and be there for my family.’
Heidi – who has kids Leni, 19, Lou, 13, Henry, 17, and Johan, 16, with ex-husband Seal – went on to add that when it comes to celebrations for the big day, she left the planning in the hands of her husband.
She said: ‘I passed the buck to my husband! Because usually, I’m the one, for the four kids, I always come up with a big party or you know, obviously for my [husband].
‘So, I’m always like doing the big parties and inviting all the friends and thinking about all the shenanigans around it.
‘But I thought, “You know what? I’m, 50, honey, this party is for you to figure out, He’s taking care of it for me. So, I’m excited! I’m just gonna lean back and enjoy that day.”‘
