Fitness trainer Tom, 24, posted the photo to Twiter on Tuesday night (12 July) after driving down to Wales with marketing manager Sophie, 30, earlier that day.
In the picture, a shirtless Tom is looking at the camera while Sophie snuggles into him.
Plenty of Love Island fans were quick to share their thoughts on the recoupling, wishing the pair best and telling them to forget about what happened before.

It's been a rollercoaster ride for Tom and Sophie since Love Island started, which included making it official in the villa, splitting, reuniting, being voted the weakest couple, dealing with the arrival of Tom's ex-girlfriend Emma-Jane Woodhams, his elimination, Sophie's kiss and coupling with Katie Salmon, then Sophie's decision to quit.
Tom had to watch from home as Sophie coupled with model Katie a few days after his elimination, and they shared a kiss during a champagne-fuelled date. But after learning a viewer's tweet had compared her to islander Terry Walsh, Sophie did a U-Turn on the situation with Katie, cooling things down and then walking from the villa to be with Tom.
Leaving the villa, Sophie was adamant she'd do whatever it took to sort things out with Tom, while he initially tweeted he was "done" before saying he still loved Sophie and wanted to talk to her.
Sophie told us: "I'm not going to do a Terry on him. There's far too many feelings there between me and him. It's still an open book with me and Tom – in my eyes we are still in a relationship and I've got to go home and reconcile with him as soon as possible."
Tom, meanwhile, told The Sun: "I don't trust her. I am just going to take it one step at a time and see what happened and see what she has to say .She needs to be 100 per cent honest to me… I don't want to hear any bullsh*t lies. I still love her. But I want to talk about it, I want to understand it. I want to know everything - no lies."
They met up in London earlier this week, sharing selfies showing themselves out shopping and lying on a bed watching TV. And yesterday, they drove to Wales, where Tom lives, suggesting Sophie was about to meet the family and friends.
