Christine McGuinness reportedly accused Paddy McGuinness of flirting with another woman, after initially being told he had kissed a separate TV star behind her back.
The mum-of-three, 34, is also said to have discovered secret Instagram messages between Paddy and a BBC presenter in March this year - prior to the pair deciding to split and end their marriage.
The Sun report that Christine was told about Paddy apparently growing close to a blonde TV star during Christine's stint on The Games earlier this year.
