"We're having the same problem with the Charleston we had with the Jive", he explained.
"I made a mistake which I'm very sorry for and for all the hurt I've caused".
Comedian Walsh and professional dancer Jones have been at the centre of a media storm following the publication in the Sun of pictures of them locking lips, for which they have both apologised.
The debate has raged as to whether the pair should be allowed to progress further in the contest but it's a storm in a teacup for original judge Arlene Phillips who performs her new show near Eastbourne on Saturday October 13.
Speaking to the Daily Mail, he said she should have put a stop to it and added: "It's her job not only to protect her own relationship, but to protect the celebrity's and be the mentor".
"We had drinks and we made a huge mistake and I regret it deeply", he continued, struggling to hold back tears.
It was also revealed that the night after their smooch outside a London pub, Seann and Katya were training alone until 10pm.
"The 32-year-old comedian and Katya, 29, appeared on Strictly spin-off show It Takes Two on Wednesday (10Oct18) to discuss their moment of madness and his ex Rebecca Humphries" withering statement announcing she was dumping him citing emotional neglect and abuse.
Walsh is said to have apologised for the kiss "face to face" with his ex-girlfriend Rebecca Humphries.
I think that, obviously I'm sorry for the hurt that I've caused. NO relationship is ideal, it takes kindness, consideration, communication &understanding.
Ballas's interview came after former Strictly judge Arlene Phillips said she supported the decision to keep Walsh and Jones in the TV show.
"I'm not flawless, far from it, our relationship wasn't ideal, that doesn't mean that I wanted it to end the way that it finally did".
Seann and Katya are set to remain on Strictly Come Dancing despite a lot of public pressure calling for the pair to be removed from the competition.
Phillips also made the point that the nature of Katya Jones's relationship with her husband Neil is not known.
"I have a voice and will use it by saying this to any woman out there who deep down feels worthless and trapped with a man they love: Believe in yourself and your instincts".
"But the main thing for me is that me and Neil are absolutely fine that's what matters to me the most".
