Strictly Come Dancing judge Len Goodman is set to become telly's new Mr Nasty when the show returns in September.
Len, who will be back as head judge alongside Bruno Tonioli and Craig Horwood, has reportedly been testing out his new harsh judging style on the US version of the show.
America's Dancing With The Stars has both Len and Bruno on its panel, and currently sees Brit Katherine Jenkins taking part in the competition.
"Len is getting more like Simon Cowell every day. He has started to be loudly booed by the studio audience which has caused a lot of embarrassment," a source told the Daily Mail.
The insider added: "He was heckled during a recent show by fans, who called for him to be sacked after he criticised one of the couples.
"But Len is enjoying the new approach — it’s spicing things up."
Strictly Come Dancing 2012 airs from September on BBC One.
