Strictly Come Dancing star Danny Mac has said he still does not understand the mistake he made in the show's grand final.
The former Hollyoaks star and singer Louise Redknapp lost out to BBC sports presenter Ore Oduba in the last round of the dancing competition and Mac said he is still mystified by his blunder in the quickstep.
He told BBC Breakfast his professional partner, Oti Mabuse, even added extra choreography to the dance the day before the live show to impress head judge Len Goodman.
He said: "My only pressure was I didn't want to make any mistakes and I think I put that pressure on myself a bit too much.
"We take risks and Oti added a whole other round on the dancefloor the day before because we wanted to please Len and put more choreography into it and that bit went OK, surprisingly enough, and then the bit I had known for the last 10 weeks went wrong.
"It is one of those dances where, if one thing goes wrong, you can't hide it. We are joined together at the hip and I still do not know what happened.
"I must have just missed a step, I can't put my finger on it, I was gutted."
Mac made history earlier in the series when he scored the first perfect 40 for a samba and said he wanted to perform the dance just as well in the final.
He said: "I just didn't want it to be worse than the first time because the first time had gone so well so the chances of it being worse were actually quite high but it wasn't - it felt electric.
"We stood there on stage and just soaked it in, the last time we were going to do it on stage live on telly.
"We are such great friends and such a brilliant team, to be half of it was the best feeling."
Mac will soon return to the dancefloor for the Strictly Come Dancing tour but will reunite with his fiancee, Carley Stenson, for a musical stage production of Sleepless In Seattle.
He said: "I'm so pleased because we have spent so much time apart and there are not many opportunities that we will have to work with each other and this project is fantastic.
"It's going to be so great for that. Carley is such a star, she is so talented."
