The duo left fans heartbroken when they revealed they are separating on Thursday evening via social media.
Taking to her official Instagram account, 22-year-old Dani posted a statement to her 3.4 million followers which read: “Jack and I have sadly decided to part ways.
“It’s been an incredible six months and we will always have a place in our hearts for each other but sadly we have come to the realisation that it’s not meant to be in the long term.
“We both plan to stay friends. I hope you’ll all understand.”
However, just hours after the shock news, the pair could be seen playing the happy couple in the 15-second reunion advert which aired during I’m A Celebrity… Get Me Out Of Here!
In the short clip, the duo look as smitten as ever as they lovingly exchange presents and dance with their fellow Love Island stars.
Dani and her 27-year-old ex had recently moved in together but a source told The Sun that their hectic work schedules caused problems between the pair.
“When they left the villa they really thought they would stay together forever, but reality soon set in and things started to get strained,” the insider told the publication.
The continued: “They came out to a whirlwind of publicity and after a while, things started to get to them and the cracks appeared.
“They are both incredibly busy and they have decided to call time on their romance.”
The Christmas reunion advert was filmed at the end of November when Jack and Dani were still together.
Megan Barton Hanson and Wes Nelson, Kaz Crossley and Josh Denzel, and Adam Collard and Zara McDermott are now the only couples to still be together from the show.
Presenter Caroline Flack will be reuniting 19 members of the 2018 cast for the Christmas special on Monday, December 17 at 9pm on ITV2.
And we’re sure it’s going to make for some explosive and slightly uncomfortable viewing…
