Simone Biles and her fiancé, NFL star Jonathan Owens, have been packing on the PDA as they continue to enjoy their romantic vacation in Turks and Caicos.

The newly-engaged couple traveled to the tropical archipelago earlier this week to celebrate the Olympic gymnast’s 25th birthday in style, and they couldn’t look more in love.

Biles took to Instagram on Wednesday to share a photo of her husband-to-be lovingly caressing her backside while they shared a kiss in front of the crystal blue water.

‘Feelin good, livin better,’ she captioned the playful snapshot, which was taken earlier this week.

‘Used to think vacation meant Niagara Falls,’ commented Owens, 26, who had shared the same image a few days before while paying tribute to his wife-to-be on her birthday on Monday, March 14.

His post also featured others snapshots from their trip, including their boat ride that afternoon, them on the beach, and them enjoying the nightlife in Turks and Caicos.

Biles, meanwhile, documented their latest boat ride on her Instagram Stories, including her glass of white and the crystal blue water

‘Want to wish my beautiful fiancée a happy birthday!!! What’s a better place to bring it in than paradise,’ the Houston Texans safety wrote in the caption.

‘Looking forward to making endless memories with you on this journey of life together, everything happens for a reason and it’s obvious we were made for each other.

‘Here’s to your best birthday yet, and we just getting started!!!! More surprises to come. I love you more than you would ever know baby #twentyfiiiiine.’

‘Wear your greens kids,’ she wrote.

Biles is never one to repeat looks, and she also modeled a white two-piece and matching cover-up while enjoying a boat ride that day.

She showed off her look in videos posted on her Instagram Stories, panning the camera first to herself and then the water. She also snapped a photo of herself holding up a glass of wine while taking in the view.

Owens, meanwhile, shared two photos of them cuddled up on the boat together, writing: ‘Only lyin’ I do is lyin’ out in the tropics.’

Earlier this week, they enjoyed a night on the town ahead of Biles’ 25th birthday on Monday

The couple has been enjoying plenty of fun in the sun since their arrival earlier this week, starting with an earlier boat ride that they both chronicled on Instagram.

When the sun went down that night, they headed to a nightclub, where Biles posted videos of herself taking shots and dancing with Owens right before the clock struck midnight and her birthday began.

She donned a black strapless top and matching pants for the celebration and shared a clip of Owens hugging her from behind, writing: ‘My whole heart.’

’25!!!!! 25!!!!!’ she captioned another clip, which showed her holding up a shot of alcohol to the camera.

Owens uploaded a selfie from their night out, writing, ‘Happy birthday baby,’ with a heart emoji. The next morning, he added a video of Biles dancing in a striped dress with the caption: ‘Okay birthday guurrrrl.’

Their lavish trip comes just weeks after Biles revealed that she had picked out her wedding dress for her upcoming nuptials to Owens.

Less than a month after getting engaged, the gold medalist checked wedding dress shopping off her list, picking not one but two numbers for her big day, which is set for 2023.

She shared several photos from the dress-shopping trip to designer Galia Lahav’s Los Angeles boutique on March 4.

During a Q&A with fans on her Instagram Stories, the gymnast said that the first dress she tried on ‘was one of the ones I picked.’

‘The second one was about eight in I’m guessing,’ she added.

Owens included a snapshot of Biles in the striped dress when he paid tribute to her in a heartwarming Instagram post on Monday, March 14, her birthday

Owens shared a carousel of images from their trip, including their earlier boat right and walks on the beach

‘Want to wish my beautiful fiancée a happy birthday!!! What’s a better place to bring it in than paradise,’ the Houston Texans safety wrote in the caption

While she didn’t share any pictures of the dresses that she actually chose, Lahav posted some snaps of her trying on two stunning gowns that did not make the final cut. The styles seemed to indicate that she had embraced the traditional route.

In one shot, she was seen wearing a rather revealing gown with a plunging neckline and sheer sides, offering a peek of skin underneath.

The skirt was a romantic tulle design with glittering floral embroidery and a train that spanned several feet behind her.

In another photo, she wore a strapless white dress with beaded lace, but this time the skirt was a more form-fitting mermaid cut.

The star also posed for a few pictures in cutoff jean shorts, a white tank top, and a white cardigan, which she wore to the fitting.

‘Looking forward to making endless memories with you on this journey of life together, everything happens for a reason and it’s obvious we were made for each other,’ he added

Biles couldn’t resist taking a few snapshots of her husband-to-be perusing the menu during their trip

The engaged couple couldn’t look more in love in the photos they’ve shared from their trip

She held up two framed signs: The first read ‘Officially a #GLbride’ while the second read, ‘I said yes at Galia Lahav LA.’

Galia Lahav’s ready-to-wear bridal gowns range in price from $2,190 to $4,960 online, though neither of the dresses Biles was pictured in on Instagram is available on the site. One of the dresses, the strapless one, is a made-to-order design.

Owens popped the question to Biles on Valentine’s Day, presenting her with an oval three-carat diamond ring designed by jeweler ZoFrost.

Jewelry designer ZoFrost, of ZoFrost & Co, revealed to DailyMail.com that the design was a team effort, with Owens handpicking the ‘perfect diamond’ himself.

It’s a three-carat oval stone with F color and VVS2 clarity.

ZoFrost said they started working together several months ago and added the extra smaller diamonds for a special touch.

Biles recently opened up about how surprised she was that Owens popped the question after two years of dating, saying she didn’t expect it.

‘I was completely clueless because it was Valentine’s Day, so it was like, whatever, it’s normal,’ she said in a video.

‘When we got there, the guy was like, “Hey, I’m taking pictures of all the couples coming through,” yada yada, so I really had no idea.’

Biles has already shared some of their plans for their big day, revealing that they will be having a ‘destination wedding’ on a beach somewhere — they just don’t know where yet.

The couple shared photos of their engagement on Instagram the next day

Biles said she was totally surprised when Owens proposed. Though he had a special night planned, it seemed normal to her because it was Valentine’s Day

Owens chose a three-carat stone that is an F color. F is a high-quality diamond that’s considered colorless, with only slight color detected by an expert gemologists

‘Wedding planning has been going well so far, it’s so exciting for me, I’m obsessed,’ she wrote. ‘I don’t think I’ll be a bridezilla because I’m making sure I know exactly what I want. Also I’ll definitely hire a planner [because] between this and building a house, our hands are full.’

Biles and Owens are likely building their house in her hometown of Houston, as she told a fan: ‘Houston will always be my home no matter what happens.’

She added that it’s ‘tough’ to settle in a single place because Owens’ NFL career makes things ‘uncertain’ — but even if he were to end up on another team, they’d be in Houston during the off-season.

When responding to a fan who asked if they want children, Biles said she hopes that they will have kids ‘one day’ and it is ‘definitely [in their] future plans,’ but they are ‘taking everything one step at a time.’

‘I want two kids. He always says he wants a football team, but he usually says three,’ she said in a video.
