While some fans admired her svelte physique in the comments section, other comments were less enthusiastic.

One fan remarked: “It’s great but I think she has lost a lot of weight”, with another joining in with: “I agree I think she’s looking too skinny. Gorgeous lady she doesn’t want to look sickly”.

Sam, 37, who makes a living as a personal trainer and fitness guru, explained that Snez has simply upped her training ahead of their wedding next year. 

“She’s a really happy healthy weight at the moment and has said she doesn’t want to lose any more. Just get fitter and stronger.

“She’s training hard and eating lots as we are getting married at the end of the year.”

Snezana and Sam welcomed baby daughter Willow in October last year – a little sister for 13-year-old Eve, who is Snez’s daughter from a previous relationship.
