Wynne Evans showed off his noticeably trimmer frame as he headed to a London hotel with the Strictly Come Dancing crew on Monday.
The Go Compare opera star, 52, lost a staggering six stone ahead of competing on the show after being motivated to change because he was struggling to even get up the stairs.
And the gruelling rehearsals certainly seemed to be paying off as Wynne looked the picture of happiness after a tiring day in the studios practicing routines.
The show will launch on 14th September with the latest batch of celebrity contestants paired with the professional dancers before the first live show on September 21.
Shayne Ward, Gladiator star Montell Douglas and Toyah Willcox also headed to the hotel as well as Sam Quek and Dr Punam Krishan.

The opera singer has been on a health kick after his weight crept up to 22 stone.
Wynne previously revealed his size increased following his marriage breakdown and the loss of both his parents.
The father-of-two went on to say that he continued working on the radio during the difficult time: 'The strapline of my show is, "cheering Wales up by one o'clock," but I was going through the worst depression, clinical depression.
'I would think about (suicide), I would try and action it... I couldn't see a way out; I couldn't see a way of ever being happy again.'

Speaking about his impressive weight loss last year, Wynne said he decided to slim down when he had 'trouble getting up the stairs'.
He said on This Morning : 'I feel great actually, it's been calories. I've always been fat, I thought ''I've got to do something''.
'I was having trouble washing and getting up the stairs. My mental health hasn't been great in the last five or six years, and it really helped.'
The father-of-two is best known for appearing the adverts for Go Compare, a role that's lasted 14 years.
However, the Welsh tenor had a successful career before making it on TV.
He was cast as Ubaldo Piangi, in the 25th Anniversary production of Andrew Lloyd Webber's The Phantom of the Opera at the Royal Albert Hall and has sung at 30 Welsh international rugby matches.

'I had no idea that the commercials were going to become so massive, but they have completely changed my life,' he told MailOnline.
'Now, I have financial security, an album deal, a little bit of celebrity, everything you dream of.'
The adverts featuring the opera-singing mascot have previously been named the number one most annoying advert in the UK.
