STRICTLY judge Craig Revel Horwood didn't hold back as he spoke about one of the show's fan favourites on It Takes Two tonight.
The 59-year-old said that the celebrity "still needs to work on a lot of things".
Craig appeared on this evening's instalment of the Strictly spin-off with host Fleur East.
During their chat, Fleur asked him why he was giving Chris MacCausland such low scores - on average he's been giving him 6.
Craig said: "He still needs to work on a lot of things.
"Yes, I think that people at home are falling in love with him, which is absolutely fine, but technically his frame is not great.

Chris is partnered with Dianne Buswell in the BBC competition.
The pair placed eighth on the leaderboard last week with 29 points.
Last month Chris took a swipe at the judges and show bosses.
Chris McCausland, 47, was the first celebrity to take to the dance floor on Halloween week.
Chris made a dig at show bosses as he warned them that he would be "having words" if he had to do it again.
"It was horrible," the comedian joked. "I didn't like going on first and if they put me on first again, we're gonna be having words."
After his dance, the judges said that there was "too much bounce".
"I overcompensated with enthusiasm. And basically, you're not allowed to be enthusiastic doing a samba," he sarcastically quipped.
Adding: "You're not allowed to have fun. I had too much fun, and I got penalised for it."
