The 67-year-old, the ballroom dancing show's head panelist, is apparently set to become more like rival X Factor star Simon Cowell.
"Len is getting more like Simon Cowell every day," a source told the Daily Mail. "He has started to be loudly booed by the studio audience, which has caused a lot of embarrassment."
Referring to his role on US show Dancing with the Stars, 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."
The BBC is currently on the look-out for a replacement for Alesha Dixon, who defected to ITV's Britain's Got Talent in January.
Goodman is expected to return to the panel alongside Bruno Tonioli and Craig Revel Horwood.
