Former CBB star Calum confirmed the breakup via a heartfelt message on Instagram, calling himself a "single man" and saying: "I wish Ianthe nothing but health and happiness. Amazing times shared came to an end. Onwards and upwards, much love."
According to The Sun, former Made In Chelsea star Ianthe dumped Calum when she found him partying in a hotel room with a load of his pals, including women.
A source claimed it was the final straw for model Ianthe as she is "not prepared to be with someone who won't compromise."
It hasn't been smooth sailing for the pair, who previously broke up in May. At the time Calum referred to Ianthe as "the first girl I really loved." The couple reuniited a few weeks later, confirming they were back with some loved up snaps.
The break up comes as a surprise, both Ianthe and Calum appeared blissfully happy back in June as they enjoyed a roof terrace lunch in Fulham, London.
