Singer Lulu, Harry Judd from McFly and ex-Neighbours stars Jason Donovan and Holly Valance have all agreed to take part in the show, The Sun reports.
Other celebrities who have signed up for Strictly Come Dancing, which launches next Saturday, include Daybreak's sports presenter Dan Lobb, Waterloo Road actress Chelsee Healey and impressionist Rory Bremner.
Ex-EastEnders star Anita Dobson and Sven-Goran Eriksson's ex Nancy Dell'Olio have also joined the BBC One competition, as has astrologer Russell Grant after recovering from his back injury in time.
One Show presenter Alex Jones and former MP Edwina Currie complete the present lineup, with bosses still looking for two male stars to make the number of celebrities up to 14. Former boxer Audley Harrison is said to be one of the males in the running.
Judd won a Strictly Come Dancing Children In Need special last year with one of the show's professional dancers Ola Jordan. Producers are apparently considering pairing the couple again.
Speaking of the lineup, a source said: "Lulu is lots of fun and will bring in viewers who remember her from the Sixties - but also younger fans who know her from her duet with Take That on 'Relight My Fire'. Harry will tick the heartthrob box."
The BBC will officially confirm the Strictly Come Dancing lineup on The One Show on Tuesday.
Dolly Parton will perform on the series premiere of Strictly Come Dancing, which will not clash with The X Factor this year.
