Speaking to Phillip Schofield and Holly Willoughby on Wednesday's (30 November) episode of 'This Morning', he said: "Poor old Ed!"
Strictly Come Dancing evictee Ed Balls shook off his "sex symbol" status before showing off his "snake hips" during an appearance on Loose Women.
The head judge will be stepping down from the show at the end of the current series but will appear in the Christmas special, which will be his last outing on the panel.
He confirmed his exit in July, and now, Len has said he is "sure" he'll be regretting his decision when Strictly starts back up again next year.
"I'm hoping we might see him dance, because Len's a fantastic dancer, ' Craig recently said of the 72-year-old". Craig's (Revel Horwood) a little bit finickity, you know "your thumb was up", whatever, I think the balance of the judges is terrific.
If I had set out for a political comeback I'm not sure I would have channelled Zoolander.
Revealing his thoughts on the potential victor, Len admitted: "This is what's great this year - usually I think it should be someone - but should it be Louise?"
'It is an honour being part of the wonderful Strictly Come Dancing family and I'm looking forward to my last series very much and to whatever comes next'. However, you make a decision and it's the right decision at the time.
"I know that it's just a different thing".
"We British love an underdog but we get to a point we know justice is more important and it would have been an injustice if one of those [other contestants] left and he had stayed".
Mr Balls, who got the boot after losing in the dance-off to Judge Rinder, said: "My time on Strictly has been incredible. It's so close. This is the first year I can hand on heart say that whoever wins is alright with me, because it's been such a great series".
The former Morley and Outwood MP has been announced as one of the famous names who will be taking part in the TV programme's live tour early next year.
