It takes more than perfect bone structure and out-of-this-world curves to make it as a Victoria's Secret model, like an intense diet and exercise regime, according to Twitter updates from Angels walking in the catwalk show later today.

VICTORIA'S SECRET ICONIC ANGELS

Sexy Brazilian Angel Adriana Lima, who gave birth to her second daughter just two months ago, is back to her fighting fit pre-pregnancy shape thanks to rigorous workouts and boxing sessions. The model's trainer, Michael Olajide, Jr., posted a pic of Lima breaking out a sweat in her boxing gloves, captioned: 'Eye of the Tigress... this Wednesday will be a KNOCKOUT. :) good luck!'

Blonde stunner Candice Swanepoel also showed followers the results of her intensive training regime, posting an image of her bruised and battered hands with the phrase: 'Boxing knuckles #notsosexy#VSfashionshow' as well as a pic of her super-toned tummy: 'Two days left till the #VSfashionshow rrraaauuwwwr!'

Meanwhile, fellow Angel Doutzen Kroes revealed some of the diet secrets of the lingerie-clad models when she posted an image to her Twitter account of the ingredients in her morning shake, which includes chocolate powder, acai powder, organic shredded coconut, flaxseed, hunza mulberries, raw chia seeds and Goji berries. 'Good morning!,' wrote Kroes. 'This goes in my smoothie this morning:) what's your breakfast like?' Estee Lauder beauties Joan Smalls and Hilary Rhoda (who is donning Angel wings for the first time this season), also gave a glimpse into their workout regimens on Twitter, with Smalls uploading a pic of a calorie-counting watch showing that she burned 862 calories, while Rhoda tweeted: '#VSFashionShow training... You get out what you put in!' alongside a photo of herself exercising at Gotham Gym.

The catwalk spectacular is taking place at 4pm and 8pm Eastern time today, with star-studded performances from Rihanna, Justin Bieber and Bruno Mars.

Legendary Angels Miranda Kerr and Alessandra Ambrosio will also be strutting their stuff, in a bevy of dramatic crystal and beaded looks, including a Snake Charmer python creation and an oversized hibiscus flowered multicoloured costume, as well as millions of pounds' worth of jewellery, according to WWD.
