The 26-year-old heated up the chilly conditions in the studio with a plunging cream-coloured gown as she carried on her hosting duties.
Holly watched on as Irish singer Samantha Mumba became the third contestant to be voted out of the competition.
The 25-year-old lost out to athlete Steve Backley in a tense showdown during Sunday night's show.
Holly says she much prefers her position away from the rink, admitting: "I'm not sure I'd be brave enough to enter."
"I'm bad enough just watching the contestants on Sunday's shows.
"And even with poor Michael Underwood having to pull out, I'll stick to my high heels rather than launch a bid to replace him."
