Louis, who was recently snapped passionately kissing Zara, is seen bringing out his playful side as they enjoyed a tropical adventure in Costa Rica. They were seen browsing local spots, as the newly loved-up couple embraced and kissed.

Zara looked radiant in a white strapless top and matching trousers, with a turquoise tie neck bikini under her top – ready for any adventure her romantic trip with Louis might offer. She accessorised her look with a pair of gold hoop earrings and a beige cap to cover her hair, which was tied in an adorable plait.

The former Love Island beauty turned documentary-maker kept her valuables in a designer bag for the outing, which comprised of wicker-style material and leather straps.

Meanwhile, Louis wore a pair of white shorts with a pastel orange top and sunglasses as he gave Zara a smooch, his tatted arm wrapped around Zara’s waist as he cheekily rested his hand on her bottom and gave her a kiss, which was warmly received by Zara as she affectionately put her hand on Louis’ neck.

The loved-up lad looked incredibly relaxed in Zara’s company as he puffed on a cigarette and struck a pose as if he was dancing. Meanwhile, it seemed the pair are enjoying being playful with one another as one photo sees Louis and Zara mucking about together – with him pretending to look serious while placing a hand on Zara’s chest and extending out his arm, a move which received a big grin from smitten reality star Zara, who is seen affectionately holding Louis’ wrist.

The playful moment then saw the pair both descend into wide smiles, with them both grinning from ear to ear as they mucked around with one another.

Later, to add to the already action-packed trip, Louis and Zara were seen hopping on a red ATV quad bike which saw the Bigger Than Me crooner take charge as he steered the vehicle while Zara sat behind him and took in the sights around her.

Earlier this month it was reported Zara flew 5,000 miles to join Louis for a romantic trip while he worked on his upcoming album. It’s been claimed by insiders that Louis splashed thousands for Zara to join him, flying her first class from London to Costa Rica after she attended the TV BAFTAs.

The pair first struck up romance rumours earlier this year as they were photographed on a cosy date in Suffolk in March, just a few weeks after Zara’s split from her long-term boyfriend Sam Thompson, who is now dating Samie Elishi.

Louis and Zara then enjoyed a cosy trip together in Los Angeles, with Zara finally unveiling her romance on Instagram as the pair enjoyed a brunch date together.

Since then, it appears their romance has continued to hot up as Zara is now supporting Louis in Costa Rica. But, she won’t be in the stands of Old Trafford for Soccer Aid as Louis is set to play alongside Zara’s ex Sam for the charity match next month.
