The Wanted’s Jay is favourite to scoop the title in the current BBC series, which also saw routines from Call the midwife actress Helen.
EastEnders favourite Jake, who plays Max Branning, starred in the Saturday night show last year.
They will join celebrity dancers Frankie Bridge from The Saturdays, actress Georgia May Foote from Coronation Street, Celebrity chef Ainsley Harriott and TV presenter Anita Rani on the tour, which finishes at North Greenwich on February 13 and 14.
The Great British Bake Off host Mel Giedroyc will swap roulades for rumbas to host all 30 date alongside judges Craig Revel Horwood who directs the tour, Len Goodman and Bruno Tonioli.
Their professional dance partners for the show have also been revealed, with Jay paired with his on-screen tutor, Aliona Vilani.
Jay said: “I’m used to performing in front of massive crowds when touring with The Wanted, but performing with Aliona on the Strictly Live Tour will be a totally different experience.
“I’m loving my time on the TV series, but the idea of being back out in front of live arena audiences is something I’m very much looking forward to.
Meanwhile Jake will again pair with Janette Manrara.
“I’m so pleased that Frankie is doing the tour as well so we can enjoy reliving it all again together and I’m very happy that I’m being reunited with Janette,” he said.
February 13 and 14, various times, from £25, The O2.
