Charlotte took to the photo-sharing app to share a quote with her followers that read: "I don't care how complicated this gets, I still want you."
She added a love heart emoji alongside it, and many began to speculate whether Charlotte was indirectly referencing her ex-beau and Geordie Shore co-star Gaz Beadle.
There's no denying that their relationship history has been extremely complicated.
They've practically been on/off for the last five years, but Charlotte had appeared to shut the door on any romance with Gary, after things failed to work out yet again.
Earlier this year, she and Gary had picked up their romance while filming for Geordie Shore's Big Birthday Battle. While they had been trying to work out whether they had future together, they never made their relationship exclusive and things turned sour when Gaz headed off to film for Ex On The Beach's fifth series.
Charlotte had said she would have '100 percent committed' to Gary if he had stayed loyal to her while filming for the MTV dating show. However, news surfaced that he had slept with Jem Lucy while out in Thailand and that led to the breakdown of his relationship with Charlotte - especially as she later revealed she had been hospitalised with an ectopic pregnancy while Gary was overseas.
Gaz, meanwhile, stressed he had been single when he left for Ex On The Beach and wasn't aware of Charlotte's hospitalisation when he bedded Jem - they got together on their first night in the villa.
He has since said he regrets sleeping with his co-star on the show, while Charlotte went on to quit Geordie Shore after publicly falling out with Gary. She told fans she wanted to distance herself from him.
Still, despite ending things on bad terms (Gary recently revealed that he and Charlotte no longer speak), fans are hopeful that 'Chaz' isn't completely over.
On seeing Char's cryptic quote, many were quick to link it back to Gaz. One user commented: "@gazgshore @charlottegshore plz get back together you are meant to be." While another added: "@gazgshore please don't let anyone take you apart cause you too are really meant for each other."
Others, however, were not so convinced Charlotte had Gary in mind when sharing her latest post. Another fan added: "Why is everyone tagging G!!! It's 99.99999999% a fact it ain't him! Let it goooooooooooooo."
Both she and Gary have appeared to move on lately. While he is currently dating model and Mario Falcone's ex Emma McVey, Charlotte appeared on E4's Celebs Go Dating and fans saw her venture on several dates with a slew of normal guys (i.e. us and not a famous face) in the hope to find romance.
She had seemed pretty keen on fish factory worker Brad but in the series finale, Charlotte put an end to their romance, admitting that she didn't want to "lead him on" after realising there wasn't anything there for her.
