The former 'Waterloo Road' star looked like she'd been raiding the wardrobe department of the BBC One show as she stepped out last night wearing a sparkly silver catsuit.
She was partying with a group of pals, including notorious ladies' man Calum Best, at the Loaded magazine bash at London's Dstrkt nightclub.
But Chelsee almost didn't make it out after being left exhausted from her 'Strictly' training with her old professional partner Pasha Kovalev.
She is set to return to the show along with other former stars including Kelly Brook, newsreader Natasha Kaplinksy, former S Clubber Rachel Stevens and athlete Colin Jackson for a festive special.
Writing on her Twitter page before heading out, she said: "Feel sooo tired room service and duvet time."
Last year's runner up also posted a picture of the pair as they reunited in rehearsals earlier in the day.
The 'Strictly Come Dancing Christmas Special' is set to air on Christmas Day.
