Jack O'Connell can't travel to the UK as his filming schedules are tight, meaning Tulisa kept having to fly over to Eastern Europe in order to spend any time with her new beau.
A source told the Mirror: "A long-distance relationship just wasn't working so the pair sat down together over dinner, and talked it through like adults. It was a fairly mutual decision and although she's really sad to split from Jack, she knows it is for the best."
The 23-year-old put on her work face at the X Factor auditions in Newcastle yesterday.
Tulisa started dating Jack O'Connell in March after her 18-month relationshop with N-Dubz bandmate Fazer ended.
