Serial killer Rose West is said to be obsessed with ITV's Dancing On Ice and tunes in every week from prison in Yorkshire.
The 67-year-old is serving a life sentence at HM Prison New Hall for the murders of 10 young women with her husband Fred West, who committed suicide in 1995 while awaiting trial.
According to The Sun, West follows the ITV dance contest avidly and even has friends vote for her favourites on her behalf.
"Rose is a huge fan. Every weekend she clears a slot in her evening to watch the latest episode - it's a big part of her prison life," a source told the newspaper.
"She's got a friend outside prison who she chats to and who makes the call to put a vote in for Rose.
"If you were the dancer she was backing, it'd be enough to send a shiver down your spine."
The semi-final episode of this year's series airs Sunday night on ITV.
