She has one of the most enviable bodies in the business.

But Home and Away star Pia Whitesell (née Miller) doesn’t think she is that fit.

The 39-year-old Chilean beauty made the surprising admission during an Instagram Q&A with her fans on Wednesday.

When asked how she stays in shape, she said: ‘I wouldn’t say I am particularly fit, but I try and do Pilates three times a week’.

She also admitted she doesn’t follow any specific diet and ‘eats everything’.

Pia said while she tries to be healthy most of the time, she can’t say no to cheese and wine.

Back in 2017, Pia told Women’s Health her day on a plate usually consists of gourmet porridge for breakfast, salad for lunch and Mexican bowls for dinner with brown rice, beans, corn and chicken/beef or ‘whatever her sons feel like’.

She added that she snacks on celery and carrot sticks, dips, pitas and a piece of chocolate throughout the day.

The model and actress is an avid fan of Fluidform Pilates, and was often seen at the franchise’s Sydney studio before relocating to Los Angeles to be with her husband Patrick Whitesell last year.

‘I practise Fluidform Pilates and I’m still really active with my boys [sons Isaiah, 18, and Lennox, 14],’ she previously said.

When she’s not able to go to the gym, she likes to swim or do other kinds of cardio workouts.

Meanwhile, Pia and her husband Patrick recently welcomed a new addition to their family.

The brunette beauty and her multi-millionaire Hollywood agent spouse, 57, adopted an adorable Border Collie Pomeranian mix, with Pia introducing the pup to her Instagram fans on Mother’s Day.

Pia shared a sweet snap of her pooch to Instagram and wrote: ‘We rescued this little guy today.’
