His career as a performer has required him to be in tip top physical shape.
But 12 years after the members officially disbanded at the height of their career, Antony Costa was a far cry from his boyband days, seen stepping out in Windsor on Sunday in an ill-fitting coat.
The singer, 35, looked almost unrecognisable as he smoked a cigarette while wearing a double breasted mac fastened at the middle with just one button.

Despite maintaining his slick sense of style, the singer’s jacket made for a slightly more snug fit around the middle.
Antony donned an all black ensemble underneath his coat and opted for a pair of comfortable trainers on his feet.
Switching up his look, the actor later ditched his mac for a denim jacket and loose-fitting white T-shirt, along with a pair of Chelsea boots.
He had been in Windsor for a charity event and is currently preparing to reunite with Blue later this year.

Following in the footsteps of a slew of other 90s and Noughties bands, the four-piece announced in January this year, that they were planning on reforming.
Antony revealed to Daily Star that Blue have several gigs lined up for 2017, after a successful stint on the road last year.
He said: ‘Me and the boys did a few gigs last year and we’ve got some gigs coming up in 2017.
‘We just keep doing what we’re doing, as obviously [we’ve] got our own individual stuff too.’

He had initially started out as an actor, before his time in Blue, and had appeared in Grange Hill.
Blue originally went their separate ways in 2005, after hits like All Rise, Too Close and Sorry Seems to be the Hardest Word.
