'So ageless': Sonia Kruger stuns in skintight dress during Big Brother premiere

Sonia Kruger has stunned in a new Instagram photo, with fans claiming the 54-year-old looks ‘ageless’ in the snap.

Last night saw Sonia hit our screens for the premiere of Big Brother, six years after the show was axed in Australia.

Sonia, who dumped Channel Nine for Channel Seven last year, took to her Instagram page to herald the beginning of the new season of the show, looking stunning in a skintight purple Mugler dress.

“Dear Diary....Room, It's been a minute. I can't believe @bigbrotherau is finally back! And he's ready to wreak havoc,” Sonia wrote.

The TV presenter accessorised her look with a pair of Isabel Marant earrings, George Jensen rings and metallic Casadei heels.

“Who cares about the housemates . It's all about Sonia!!! Slay,” one person commented on the photo, while another simply said:”So ageless and stunning”.

“Well @SoniaKruger is looking younger than ever,” a fan said, with another agreeding, commenting: “Wow just wow! What a knockout.”

Last year, Sonia launched her own dance-based fitness and diet program, Strictly You, after people kept asking her how she got her incredible figure.

In an interview with The Australian Women’s Weekly, Sonia said the idea for the program was born after people kept questioning her own health and fitness habits.

"This is actually half the reason I did this, because people were sort of saying to me 'What do you do? What do you eat? What workout do you do? How do you get your arms to look like that?" Sonia said.

"Even now, if I post a picture on Instagram from The Voice I get so many questions from people about what I'm doing, what am I eating, what sort of workouts do you do, so it felt like a natural step to do this and to share it."

“And now women 50 plus, 60 plus are still very vital and vibrant, as they should be." she said.
