Horwood said that Dell'Olio was a lost cause for pro dancer Anton Du Beke, after they hit the bottom of the Judges' Leaderboard on Saturday for their salsa.
Asked for his advice ahead of Dell'Olio and Du Beke's tango this weekend, Horwood told It Takes Two: "Not a lot. I have no advice other than pray, darling.
"She's been going at him like a lobster. I have no idea what I would do facing that."
Dell'Olio only picked up 14 points for her salsa and was accused of dancing like a drunk by judge Bruno Tonioli.
"Champagne, champagne, have you had some champagne today? It looks like you'd had two gallons," he said.
"You had no idea... I think you broke records for how many times someone can go wrong in this competition."
Earlier today, rival contestant Edwina Currie insisted that Dell'Olio hadn't been drinking before the show went on air.
"I did not see Nancy drinking before the show, I can say that definitely," she told This Morning. "But I suspect Nancy's performance would've been much the same anyway!"
