The 40-year-old was in a relationship with Kaszubowski for four months but called it quits after realising he was not the one for her, reported Daily Mirror.
"It's over, Geri finished it with him because she just thinks that he is really, really boring. She realised that Anton wasn't really doing it for her and he wasn't keeping her interested.
"Geri is incredibly high maintenance and Anton found her quite difficult to be with at times but he really fell for her. She demanded a lot from him but as usual with Geri, it's very hard to keep her happy," a source said.
