The two former Australian soap stars topped the judges' scoreboards after the first weekend of shows and are also the most popular celebrities with readers of Digital Spy.
Donovan picked up 32 points for his cha cha cha with Kristina Rihanoff on Saturday night, while Valance and Artem Chigvintsev earned 28 and topped the board on Friday with the same dance.
In two Digital Spy polls over the weekend, thousands of Strictly fans picked the pair out as their early favourites.
Donovan picked up a huge 48.1% on Saturday, while Valance notched up 31.2% on Friday. Harry Judd from McFly, astrologer Russell Grant and former soap star Anita Dobson are their closest competition at the moment.
Strictly continues on Saturday at 6.05pm when the celebrities will be dancing foxtrots and salsas, followed by the first elimination on Sunday.
