Former Strictly Come Dancing contestant Russell Grant has suggested that Kimberley Walsh and Denise Van Outen won't benefit from their past experience.
Both girls, who have backgrounds in performing and musical theatre, were confirmed on Monday as part of this year's Strictly line up.
While Denise has worked on both the West End and Broadway for years, Kimberley has been a part of Girls Aloud for a decade and recently also began performing on the West End.
It's led to some claims that they'll be at a very unfair advantage over some of the other contestants when it comes to launch night this weekend.
Speaking on BBC Breakfast this week, Russell said: "I know there is a bit of worry about Denise Van Outen or Kimberley Walsh who have appeared in musical theatre, but it’s a very different form of dance.
"The kind of dancing that you do in musical theatre, it’s not the same as learning Latin and ballroom, which is very stylized and very technical.”
Denise previously insisted that she couldn't dance that well, despite her past.
"I can move. I can do the basics. I’ve got the basic dance skills thanks to theatre school. But this is all really new to me, and I haven’t danced properly for about 15 years," she said. “I’d give myself maybe a four out of ten. I’m most nervous about the fact that people will think I can dance already because of my stage career, but I’ve actually never had a true dancing role.”
She added: “That’s what I worry about the most, people thinking I’m a dancer when I’m not.”
Meanwhile Russell Grant advised this year's contestants to give their lives to the show!
He said: “You’ve got to give your life over to it. It’s 24/7, don’t think you can turn up on a Friday and do a bit of a rehearsal and then appear on Saturday. This year it is going to be much more based on the technical side, how good you are at the dance.”
