Toned: Miranda happily displays her taut stomach and enviable curves in a hot pink bikini and denim hotpants
It's not hard to see what first attracted Orlando Bloom to girlfriend Miranda Kerr.
The stunning model, who has been dating Pirates of the Caribbean star Orlando for the past three years, showed off her enviable curves as she celebrated the 15th Anniversary of the Victoria's Secret Swim Catalogue.
Wearing a shockingly bright pink bikini, Miranda, 26, looked toned and tanned as she posed for photographs, but the Australian star admits she has to work to maintain her svelte figure.
She said: 'The first step is eating healthy. I predominantly eat organic when I can. I eat extremely healthy because when I do, I have more energy.
'I love spinach, avocado, lots of greens and broccoli.'
However, Miranda admitted she does sometimes enjoy a treat and occasionally likes to splurge on fattening foods.
She added to E Online: 'I'm pretty much 80 percent healthy, 20 percent indulgent, because I don't believe in depriving yourself.'

While Miranda was criticised earlier this year for her tiny frame, the model insists she takes her responsibility as a role model seriously, and would never put her health in danger.
She explained: 'As soon as you step into the public eye you need to take responsibility for the people you are influencing.
'Body image is something that the majority of young women struggle with and I do think it is important that models are seen to be healthy and at a weight that works for their body type.'

But, unlike some celebrities who claim they are blessed with toned figures that do not need exercise to maintain, Miranda is refreshingly honest about her workout regime.
As well as enjoying yoga, Pilates and weight training, Miranda also likes 'to go on the stepping machine if I'm a hotel and I can't get outside.'
Miranda, who has worked with Victoria's Secret since 2007, also revealed her tips for choosing the right bikini to flatter your body shape.

She said: 'Everyone has different body shapes so it's best to find a swimsuit that flatters your individual shape.But most importantly, with the right attitude and confidence any swimsuit will look good!'
A keen advocate of practising what you preach, Miranda recently starred in a cheeky 'Bikini Mixer' video for the lingerie company, where she shows off her figure in a series of bikinis and even displays her flexibility by performing the splits.
