LOUIS Tomlinson and Zara McDermott’s chemistry was on full display during their Costa Rica holiday.
The One Direction star and Love Island beauty couldn’t keep their hands off each other on a sun-soaked day out.
They were spotted hiring a quad bike, with Louis, 33, taking the lead as they cruised through town.
The History singer wore an orrange T-shirt and white shorts, which he teamed with black sunglasses and a baseball cap.
Zara, 28, stunned in loose white trousers and a crop top layered over her green bikini.
At one point Louis puffed on a cigarette while they waited for their ride, with a smitten Zara wrapping her arms around him.

Louis returned the affection by gently squeezing her bum and planting a kiss.
They were later seen grinning at each other before hopping on the quad bike and driving away.
Louis flew the Strictly star out in first class to a secluded villa last week.
He’s currently working on new music there and wanted to spend some quality time with Zara after going public with their romance.
She was previously seen locking lips with her new pop star beau as they dined at a restaurant.
A source said: “Louis and Zara are going from strength to strength.
“He got his team to organise her first-class travel from London to Costa Rica.
“It meant Zara was unable to attend the TV Baftas but she is keen to spend as much time with Louis as possible.”
Louis will be back in the UK for Soccer Aid next week and is set to play on the England side with Zara’s ex Sam Thompson.
Zara split from former Made In Chelsea star Sam in January, moving out of Sam’s West London home, and leaving behind the two cats they shared.
She has decided to skip Soccer Aid to avoid an awkward run-in with her ex.
Zara and Louis confirmed their romance on holiday in Los Angeles over a month ago.
The pair were snapped holding hands in a sweet PDA during their trip to the US.
The Sun revealed they were an item after they were spotted enjoying an overnight stay at The Suffolk in Aldeburgh in exclusive photos.
It came amid reports that Zara had formed close bonds with Louis’ sisters Phoebe and Daisy.
They recently teased a new reality show, with sources claiming Zara has been helping them behind the scenes thanks to her experience as a TV presenter and documentary maker.
