The 'Only Way Is Essex' star took to his Twitter account yesterday (12.03.15) to announce he is quitting the ITVBe show and also appeared to end his relationship with his girlfriend of five years, leaving Ferne devastated.

A source shared: "Ferne is heartbroken that Charlie has taken to Twitter but it's all very raw so who knows what will happen. Hopefully he will realise he can't dictate her career, it feels unfair to suddenly and from nowhere put her in this position.

"She's hoping he'll realise this and they'll make it up but right now Ferne is unsure what to do and is just very upset."

Charlie's outburst came after months of arguments between Ferne and his older sister Chloe Sims, who also stars in TOWIE, and he's said to have forced his girlfriend to choose between him and the show.

The insider told the Daily Mirror newspaper: "Unfortunately Charlie has given Ferne an ultimatum - it's him or the show. This came as a huge shock to Ferne who is really upset that he would put her in such a position.

"She loves being part of TOWIE and is an important character who is great for the show.

"The reality is that Charlie has never wanted to live his life on camera. Ferne has promised to support him either way and just wants him to do the same for her.

"She has been proactively encouraging him to make amends with Chloe and his family but the fact everyone wrongly thinks she is to blame for Charlie and Chloe falling out has put a strain on their relationship."

The messages posted on Twitter by Charlie, 23 - who took a break from the show last year after struggling to cope with the drama between his sister and girlfriend - suggested Ferne had chosen TOWIE over him.

He wrote: I wish @Chloe_Sims and @fernemccann the best with their lives. But always live knowing you chose the show... (sic)."
