They renew their vows every single year and it's safe to say that Seal and Heidi Klum are a couple very much in love.
And it appears that the German model and her singer husband have no problems displaying their affection and were seen doing just that as they soaked up the sunshine in Sardinia.
The couple were seen lying on a pontoon in the sea and they couldn't resist indulging in a number of passionate kisses as they relaxed on holiday.

Seal showed off his statuesque figure in a pair of small bright red speedos while Heidi displayed her model figure in a pretty sequin embellished bikini.
And it was certainly a family affair as their children, Leni, seven, Henry, five, joined the couple out on the floating platform.
Hands on: Seal, dressed in his red Speedos emerged from the water hand-in-hand with his wife who looked fabulous in her embellished bikini
Making a splash: The couple, who renew their wedding vows every year, appeared to be having a great time in the water together
And Harry seemed in the mood to play as he interrupted his parents as they were canoodling.
Seal appeared happy to oblige and was seen diving into the water showing off his athletic figure.

Family time: The couple were joined on the pontoon by their five-year-old son Henry who is in the mood to joke around
All together: Heidi and Seal enjoyed the day with their children, Leni, seven, who Seal adopted in 2009, and Henry
But as he hauled his frame back onto the floating platform his weight nearly tipped Heidi into the water.
As they made their way back to the beach the couple were hand-in-hand as they emerged from the water.

Cut it out: As Seal climbed back onto the pontoon he nearly tipped Heidi off with his muscular frame
And Seal and Heidi were just as amorous out of the water showing affection at almost every opportunity.
Later in the day mother-of-four Heidi was seen with their youngest child, two-year-old Lou Sulola, as they took a walk in the sand.
The family could well be one of the happiest celebrities families with Seal and Heidi no stranger to showing off their love for one another.

Every year the couple, who have been married six years, renew their wedding vows in themed ceremonies on May 10.
Yesterday Heidi was seen making the most of her holiday supping a bottle of beer while she spent time on the beach with her family.
Heidi, 38, showed off her remarkable form in a different two piece bikini she'd been wearing the day before - her ultra flat stomach still very much on display.
The black number features khaki coloured straps and detailing - slightly different to the previous day's ensemble which featured sparkling gold details on the hips.
Out of water action: As the couple spent the rest of the day on the beach they didn't miss the opportunity to show the other just how much they care
Model figure: Heidi showed off her model figure in yet another skimpy bikini while Seal showed off his muscles in a pair of barely there Speedos
Annoyingly it appears her penchant for bottled beers, Corona in this case, has had very little effect on her figure, perhaps because she consumes alcoholic beverages in moderation and still subscribes to a healthy exercise regime.
On Sunday Heidi was seen sunbathing topless in Porto Cervo, unveiling the figure that has won her contracts with numerous fashion houses around the globe and a plethora of magazine covers.
