The actress and television show host has discussed her appearance as a contestant in the forthcoming season of the BBC One reality competition.
"I've never had a spray tan in my life," Riley said. "I'm frightened of looking like an Oompa Loompa!
"I don't want to look shiny. I am incredibly pale, so I think I might look a bit ridiculous, but I'm going to throw myself into the Strictly experience 100%."
The former Emmerdale star was revealed as a contestant over the weekend, as well as EastEnders graduate Sid Owen.
The pair will compete alongside Colin Salmon, Dani Harmer, Denise Van Outen, Fern Britton, Jerry Hall, Johnny Ball, Kimberley Walsh, Louis Smith, Michael Vaughan, Nicky Byrne, Richard Arnold and Victoria Pendleton.
Strictly Come Dancing kicks off its tenth series on Saturday, September 15 at 6.30pm on BBC One.
