Instead of taking it easy following her long haul flight, the reality star was pictured in her workout gear on Tuesday (16 September), shortly after touching down at Los Angeles International Airport.
Kim, 33, had been in Australia with Kanye, 37, to support him on the Down Under dates of his 'Yeezus Tour' in Perth, Adelaide, Melbourne, Sydney and Brisbane. She also managed to fit in a few promotional appearances of her own to publicise the Kardashian Kollection launch.
The couple's one-year-old daughter North was also with them in Oz and the family were pictured enjoying a few excursions together, including a day at the Australia Zoo in Queensland.
Meanwhile, it's been reported in the US that Kim and rapper Kanye have quietly put their Bel-Air mansion up for sale.
The couple are thought to have splashed out $11 million on the estate but never actually moved in. They began a renovation project and then Kim discovered she was pregnant with North. She's since said in interviews that changed what she and Kanye wanted in a home and so they began to look elsewhere.
Earlier this year, it was said they'd found a perfect new home around the corner from Kim's mum Kris Jenner in Hidden Hills, California which they wanted to make their family house.
Kim, Kanye and North have been living with Kris for more than a year while trying to sort their own home.
Chatting with People magazine last month, Kim admitted: "Oh, I'm so ready [to move]! I am so ready to be out of my mum's house, you have no idea. But it will be nice to still be close."
