Ferne joined her co-stars at a merry St. Patrick's Day cast party, which was being filmed in Stanford-le-Hope, Essex.
Dressed in red, Ferne was pictured standing in the middle of the dance floor clutching a glass of drink of her hand.
She was also seen catching up with the girls, Gemma Collins and Danielle Armstrong, and it looked like they were in deep discussion as they sat down at a table.
Last week, Charlie announced he would no longer be starring on TOWIE while also hitting out at his sister Chloe Sims and girlfriend Ferne.
TOWIE bosses confirmed Charlie's departure, saying that he "hasn't felt comfortable sharing his real life on camera".
It later emerged that Charlie had split with Ferne after giving her an ultimatum. A source told Reveal: "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."
Since then, Charlie has publicly spoken about his departure while thanking fans for their messages of support. He said: "It's been a journey so far… Let's see what else life has to offer!"
