The 38-year-old reality star admitted "it's not been a good week" as her mum Joan has fallen ill just days after she split from her ex-boyfriend James 'Arg' Argent.

Gemma shared the upsetting news with her followers on Instagram: "My poor mummy in hospital with pneumonia coming home @joancollins1 to be right by your side I love you #itsnotbeenagoodweek."

The 'Only Way Is Essex' star kicked Arg out of her house after he embarrassed her by posting a video of her snoring in bed and he then sent her hurtful messages claiming she had "more rolls than Greggs" and branding her a "nasty mean woman".

Gemma has been filming a cameo on 'The Real Housewives of Cheshire' which she has had to leave so she can be there to support Joan.

A source told The Sun Online: "Gemma wants to be there for her mum but has to try and deal with this alongside the fact Arg still hasn't apologised to her for his comments.

"At the moment she is filming a cameo on 'The Real Housewives of Cheshire', which she is committed to despite everything else going on.

"But it has been a terrible week for her and she is devastated by everything which has happened."
