The former Geordie Shore star posted a blink-and-you'll-miss-it video to Snapchat on Thursday (23 June) showing her dropping a towel and diving into a pool while nude.
Char's currently in France for Cannes Lion, where she's been taking part in a panel discussion on the Daily Mail's yacht alongside the likes of Katie Hopkins, Gemma Collins, Jonathan Cheban and Ollie Locke.
But she admitted on Snapchat she'd missed her flight home. Oops!
Her friend Kristy Green shared more Snapchat stories from Charlotte's "naked jump", including one where a stark naked Char informs the camera she's going to do something really funny.
We wonder what it was?!
While Charlotte's in France, the rest of the Geordie Shore gang have been filming series 13 of the MTV show in party cities including Magaluf.
Char won't be joining them as she quit the series at the start of June, saying she no longer wanted to film with ex-boyfriend and co-star Gaz Beadle, following their most recent split.
She has, however, teased she'll be back on screens soon, as she's working with MTV on other ideas.
Charlotte told MTV.co.uk: "I'm massively excited for the future and - don't worry - this isn't the last you'll see of me on MTV. I'm working on a great new idea with the team there and will always be one of the 'family'."
And a producer for Geordie Shore added: "We're working with Charlotte on other new and exciting projects, and she knows the door is open for her to return to Geordie Shore when she's ready."
