The star, 33, was seen getting up close and personal with Love Island's Zara, 28, on a romantic break in Costa Rica. He was spotted playfully grabbing onto Zara's bum as they shared a passionate kiss on their tropical adventure.

Louis and Zara were seen embracing and sharing kisses as they explored their stunning surroundings. Body language expert Judi James has told the that amid the couple's blissful honeymoon period, there may be some issues at play.

She told us: "There's an air of casual sexuality from Louis here as he grabs Zara's bum to hold her to the side of his own torso as he holds a cigarette in his free hand.

"Keeping his torso facing front, suggesting an uncommitted approach, he leans in for a kiss while she is fully facing him with both her arms around him although not extended to embrace him fully, suggesting some reservation."

Judi added of a snap of the pair driving down the street on a quadbike: "Louis looks totally happy in charge of the bike, where there is an expression of total enjoyment on his face, giving the impression that he enjoys some of the playful rituals with Zara as much as the flirty ones."

She then addressed one photo that showed Louis turning away from Zara with his hand on her chest. Judi said: "But why the extended arm pushing her away in one of the photos?

"His hand is on her chest in a rather uncomfortable-looking gesture of distancing here. She looks rather surprised, with her own hand on his wrist in what looks like an attempt to stop the extended hand, while her head is cocked in a gesture suggesting puzzlement.

"But his expression is more of a facial gurn, with the lips pursed and pushed out in what is often a sign of a sulk. This sexy but unsynchronized body language and the facial gazing suggests that, although they might be close, they don't quite understand each other yet."

"One or both of them might be difficult to read, leading to a lack of mirroring or truly relaxed-looking behaviors," she concluded.
