Josh Widdicombe, Emma Willis and Johannes Radebe will take over as Strictly presenters this year, following the departures of Tess Daly and Claudia Winkleman.
The first line-up announcements were made significantly earlier than usual – the BBC usually confirms the line-up in August.
Speaking to ITV’s Good Morning Britain in June, Ballas said: “There are going to be some people on there that will make you go ‘wow’.”
Asked about the new presenting trio, Ballas said she was “very excited to see what they bring” to the show.
“I know they took lots of chemistry tests, as did everybody, and those chemistry tests have brought those three people together, and I believe it’s absolutely unbelievable,” she said.
Ballas described the number of new elements on this year’s show as “quite extraordinary”, but added that it will still feel familiar to viewers.
“I don’t think they’ll change the show too much, maybe tweaks here and there, but no major changes.”
Ballas, Craig Revel Horwood, Motsi Mabuse and Anton Du Beke will all return as judges.
Regular pro dancers including Amy Dowden, Dianne Buswell, Katya Jones, Vito Coppola and Aljaz Skorjanec will all be back on the dance floor.
However, professional dancers Gorka Marquez, Nadiya Bychkova, Luba Mushtuk, Karen Hauer and Michelle Tsiakkas will not be returning this year.
