The 23-year-old reality star – who won Celebrity Big Brother last week – was snapped arriving at the Riverside Studios in London on Wednesday (18 September) to tape the ITV2 panel show alongside Fearne Cotton, Holly Willoughby and Keith Lemon.
It appears Charlotte was on Holly's team as she tweeted after the filming: "Wanna say a huge thanks to @lemontwittor for having me last night and @hollywills for being so great and making me feel at ease! #GREATNIGHT."
And, showing we're in for an amusing night, other team leader Fearne tweeted: "Just filmed the funniest round on Celebrity Juice for tomorrow night. Tears. Actual tears."
Charlotte certainly has a new fan in Keith, who tweeted a picture of them together backstage with the caption: "Fanks for coming on't show. Love you."
Charlotte replied: "Absolutely LOVED it! I was mortal last night."
And good news for GS fans! It's not just Charlotte we'll be seeing, as she teased: "Cannot wait to watch @CelebJuice tonight! absolutely hilarious!! GeordieShore took over wit @HollyGShore Nd @SophieKasaei_ gettin involved."
The new series of Geordie Shore kicked off on MTV earlier this week, featuring new girl Marnie Simpson.
Celebrity Juice continues tonight at 10pm on ITV2.
