Charlie also shared some pictures of himself with Gemma and her mum Joan.
He commented: "A beautiful day with some very special people @missgemcollins @mrsjoancollins #whereitallbegan."
It's good to see them all hanging out again! Anyone else wishing Charlie would make a return to the ITVBe reality show?!
Charlie was first introduced during the fourth series of TOWIE in 2012 as Gemma's boyfriend, however, their relationship didn't work out.
One of Charlie's major storylines involved his friendship with best mate Bobby Norris, and subsequently with Bobby revealing that he had feelings for him. Charlie left TOWIE in 2013.
In October last year, Charlie came out as gay. He opened up about his sexuality during a live interview on ITV's This Morning, where he said: "On that show, they followed my storyline which was very much about that subject because I never really knew where I belonged.
"I never really knew where I fitted in and it was something that I had to address and it's taken me a good few years to get here now and be able to say, I'm Charlie, I'm 29 years old, I'm a gay man and I'm very comfortable with that."
