Make-up free Kate Upton wears a caramel coloured jumper with skinny jeans and cream mules as she jets out of Heathrow

She visited the UK to talk at the Vogue Festival - and Kate Upton's fleeting break came to an end when she headed back to Heathrow airport on Tuesday.

The Sports Illustrated model looked great despite not wearing any make-up as she prepared to jet back home after a trip to London's Chiltern Firehouse and an interview with Radio One. 

Kate, 22, looked lovely in a casual ensemble which consisted of a chunky knit caramel-coloured jumper which she wore over a crisp white shirt.

The lovely lady teamed the knitwear with a pair of skinny Frame Denim jeans which showed off her enviable legs and a pair of trend-led cream mules which revealed her perfect pedicure. 

Wearing a pair of designer shades, Kate carried a chic leather jacket in one hand and a vanity case in the other as she prepared to make her way through the terminal. 

Her blonde locks were blow-dried to perfection and her natural beauty shone through.

Step up your shoe game in Kate's white mules

We're just going to say it - Kate Upton is seriously on her way to becoming our number one girl crush.

Ridiculous curves, silky golden tresses and great style to boot - is there anything this girl doesn't have?! We spotted her dolled up in Dolce & Gabbanna earlier in the week, but the blonde beauty looks just as good dressed down.

We love this slouchy cream knit which Kate has paired with figure-hugging jeans and the object of our obsession - these fabulous mules. Mules are back in a big way this season - with everyone from Miu Miu to Lanvin jumping on the Seventies trend.

Kate's Tibi pair stood out to us for that wooden block heel and textured track sole detail - wear them with everything from suede wrap skirts and a blouse for work to skinnies a la Kate for weekend luxe.

So why not snap up the coolest shoe shape of the season and buy Kate's shoes now? You can shop them in a cream shade at Net-A-Porter if you click the link (right). Or head to our edit below for simlar picks from Forever 21, ASOS, Fifth label or Calvin Klein.

While Kate may have one of the best bodies in the world, the model, who wears a US size 8 (UK size 12), recently revealed she is on an extremely strict diet and exercise regime.

Kate, who appeared on the cover of the 2012 Sports Illustrated Swimsuit Issue, lives by the ABC rule: 

No alcohol, bread or processed carbohydrates, and goes through a 48-hour juice cleanse before every big film scene of photo shoot.

She told the Evening Standard: 'She told the paper: 'For me it's about being strong, having the strength to work ten-hour days and eating healthily.'

Ahead of her flight, Kate took to her Instagram account wearing a lovely gold necklace.
