Chloe was seen on the ITV2 show, hosted by Keith Lemon, last night (2 October) and Demi had accompanied her to the TV studios where the filming takes place.
As Holly Willoughby is on maternity leave, Chloe was on Gino D'Acampo's team, along with antiques legend David Dickinson.
Unsurprisingly, within minutes of the programme starting, Keith made a joke about the team's bronzed tans, branding them Team Mahogany!
Since her appearance on the show, Chloe has shared a picture of herself and Demi - who she nicknames Bam Bam - cuddling up to David.
Commenting on the snap, she said: "Me and bam Bams with #daviddickenson @demsims."
Chloe also posted a photo of herself and Demi with Celebrity Juice presenter Keith (real name Leigh Francis).
Writing next to it, she said: "With Bam Bams aka @demsims and the LEGEND @LeighFrancis loved my dress from @aqaqlive #Celebjuice."
Earlier this year, Demi made her debut on TOWIE when she was shown chatting to their brother Charlie about his fiery relationship with Ferne McCann.
Since then, Demi has switched up her her brunette hair and she is now a platinum blonde!
