As they've reminded us plenty of times, going through a break-up in the public eye can't be easy. So you'd have thought that Dani and Jack would be doing everything possible to make things easier for each other in light of their high-profile split.
However, this weekend - less than three weeks after they announced the break-up - Dani was photographed passionately kissing her ex-boyfriend Sammy Kimmence on a very public London street.
According to a friend of Dani's, she dated 23-year-old stockbroker Sammy for around a year then split from him shortly before her stint on Love Island - leaving fans more convinced than ever that Dani's relationship with Jack was all for fame.
Whilst Dani hasn't yet responded to the reports, Jack has made his feelings very clear - deleting all the pictures he had with Dani from his Instagram account and sharing a savage message on his story...
Check out the video above to see Dani with her new man - as well as Jack's savage response!
