The actress, who plays Janine Butcher in the BBC soap, is said to be progressing well in rehearsals with her mystery professional partner.
According to sources, Brooks has always been interested in participating in Strictly, but could not find time for a regular series.
"She loves Strictly but hasn't been able to commit to a full series as she's had such great storylines in EastEnders," an insider told The Sun. "So this is just perfect for her."
Torchwood actor John Barrowman won the 2010 Strictly Christmas special with his partner Kristina Rihanoff.
Fern Britton and EastEnders legend June Brown (Dot Cotton) were among the other celebrities competing in the festive edition.
