The 32-year-old singer – who is a judge on the BBC One show – thinks there will be a relationship between at least one celebrity and their professional dance partner like in other years because they spend so much time together.
She told the Daily Star Sunday newspaper: “I’m sure there will be a romance because there has been every year. The dancing is so intense and passionate it just happens.
“I don’t know who it will be but I’d bet money that there is some sort of affair. You spend so much time with each other it always seems to happen.
“The thing is, I don’t think anyone is single so that could make an interesting show.”
Last year’s winner Kara Tointon, Ali Bastian, Matt Di Angelo and Joe Calzaghe are just a few of the celebrities to have fallen for their partner in previous series.
However, Alesha doesn’t think Kara – who is still dating Artem Chigvinstev – has anything to worry about even though he is dancing with sexy Holly Valance.
She said: “People are saying Holly and Artem look great together but I don’t think it will be them. Artem is so loved-up with Kara and Holly has her billionaire boyfriend so she won’t be going anywhere.
“But it will still be hard for all the celebs’ partners to watch.”
