Serena Williams 'getting paid' for exclusive £26,000-per-week honeymoon on a private island with her husband... despite the couple being worth £111M (Details, pics)

She is a record-breaking tennis player, while he is a Reddit co-founder, and together they are worth a jaw-dropping £111M.

But new reports are claiming that Serena Williams, 36, and Alexis Ohanian, 34, could be getting their £26,000-per-week luxurious honeymoon in the Bahamas for free- or even getting paid for it.

The newly-wed couple are staying in a luxury villa at the Kamalame Cay island resort in the Bahamas, and have shared an array of envy-inducing social media snaps, leading to speculation they are promoting the luxury venue.The 3.5-bedroom, 4.5-bath luxury cottage boasts an open-concept floor plan with 20-foot peak ceilings and sits on a 96-acre privately owned resort located less than a mile off the world's largest barrier reef on Andros.

However TMZ claims the couple, who recently welcomed baby Alexis, are getting the plush getaway for free, or getting 'paid to endorse it'.

'All signs point to Serena getting either paid or a huge discount for the endorsement,' they reported.

On Tuesday Serena offered her fans a tantalizing look inside what she described as her and Alex's 'perfect honeymoon villa' on a private island in the Bahamas – as she slipped in a plug for a popular travel site.

The tennis ace and new mom posted on her Instagram page a brief video shot by her husband’s drone equipped with a camera, which shows a sprawling beach side lodge nestled among palm trees, set against a postcard-worthy tropical sunset.

The short clip was accompanied by a caption that read: 'A week in paradise. Thanks @bookingcom for helping us find the perfect honeymoon villa. #BookingYeah.'As the camera zooms in on the two-story, $35,000-per-week villa, Vanessa is seen posing up on the balcony.

As of Tuesday afternoon, the video has been viewed more than 160,000 times on Williams' page, which boasts 7.1million followers.

It is unclear whether Williams and her family were allowed to stay for free at the ritzy private resort, or received a discount, in exchange for the well-placed mention on her Instagram page.

In addition to the short video showing Williams solo, a still photo emerged depicting the multimillionaire honeymooners standing on the balcony together and gazing lovingly into each other's eyes while holding matching coffee mugs in their hands.

On his Instagram page, Ohanian also shared a photo from the resort, which shows him holding the Phantom drone used to shoot the video posted on his wife’s page. He wrote: ‘couldn’t help but fly my Phantom a bit on the honeymoon. @Serenawilliams caught me getting some spectacular shots around @kamalamecay. She just posted one of them.

'According to a People Magazine report, the video and images were taken on the Bahamian island of Kamalame Cay - a 96-acre privately owned resort located less than a mile off the world's largest barrier reef on Andros.

Williams, Ohanian and their 2-month-old daughter, Alexis Olympia, decamped to the secluded island for a nine-day getaway after tying the knot on November 16 at a star-studded celebration in New Orleans.

People Magazine reported that the power couple's honeymoon digs are comprised of the 3,600-square-foot Magnolia villa - one of nine such accommodations on the island - that is accessible only by helicopter, private boat or a seaplane.

According to the resort's site, the 3.5-bedroom, 4.5-bath luxury cottage boasts an open-concept floor plan with 20-foot peak ceilings and opens onto a 'well-appointed’ 1,500-square-foot beachfront terrace with panoramic views of the Atlantic.

Kamalame Cay - named the No 1 resort hotel in the region by Travel + Leisure Magazine this summer - offers the services of private chefs, butlers and personal trainers around the clock.

Vacationers can enjoy plant-based, gluten-free meals - and daily deliveries of freshly baked cookies. The manicured property also includes an over water spa with organic beauty products, tennis courts, a three-mile-long private beach, a seaside Tiki bar and even childcare services.

Serena and Ohanian’s honeymoon vacation, it would not be the first time that the Wimbledon winner - ranked 51st on Forbes Magazine's 2017 list of the world’s highest-paid athletes - used her Instagram page to cash in by promoting companies.

Just two days after her lavish New Orleans wedding, Williams shared a video on her social media platform showing the eight-room, $1,250-a-night mansion in the French Quarter where she and her bridesmaids stayed for free before the big day. The video has since been taken down.

Williams, who took home $27million last year in prize money and endorsement deals, according to Forbes.
