She'll be competing against radio DJ Sara Cox (who's dancing with pro Robin Windsor), West End legend Elaine Paige (who's teaming up with Pasha Kovalev), Bros singer Matt Goss (who is partnered with Aliona Vilani), 'EastEnders' actor Ricky Norwood (who has got Janette Manrara) and comedian Rufus Hound (who has been given last year's winner, Flavia Cacace).
The Saturdays star is surely going to lift the silver star trophy come Christmas Day. She'll be dancing with the wonderful Ian Waite, and they've already got a head start on the other five couples.
Rochelle took part in the 'SCD' special on 'Children In Need' in 2010 along with professional partner Ian. They danced an impressive American Smooth to McFly's 'All About You' and scored 33 (6 from Craig Revel Horwood, 9 from head judge Len Goodman, 8 from Terry Wogan and 10 from Pudsey).
They didn't win, but there's no shame in that, as they lost to Harry Judd, who danced a Paso Doble to The Saturdays' 'Ego'. Yes that's right, the same Harry who went on to win the 2011 series of 'Strictly'.
Tips from the top
Not only does Rochelle have previous experience of the dancefloor, she's also well connected to ask for advice on how to succeed in the 'Strictly Christmas Special'.
Challengers for the title
So who could give Rochelle a run for her money for the Christmas 'Strictly' title?
Well, Rufus has previous experience with his turn on 'Let's Dance for Comic Relief' in 2010. I'm not sure how useful his impersonation of Cheryl Cole's 'Fight For This Love' routine will be, though.
Ricky showed off his street dance moves on that amazing 'EastEnders' segment on 'Children In Need' this month. If he can translate that experience to the ballroom dancefloor, he could be a contender.
Matt performed on one of the 'SCD' results shows earlier this series, so he has the advantage of having been amongst it all very recently.
Elaine and Sara are big fans of the show, but that could mean they care too much and feel the pressure. Weighing all that up, I still think the Christmas trophy is Rochelle's to lose.
Bring on the LaplandUK opening sequence, the festive sparkles and yuletide routines. Oh, and Marvin in the audience plus the rest of the The Saturdays too, please.
