The 31-year-old star is seen baring her washboard stomach in a pair of loose jogging bottoms and cropped sports top as she poses and pouts for the camera.

She accompanied the shot with the caption: 'Sweatpants hair tie chillin with no make up on (sic)!'

And despite looking less than red carpet ready in the outfit, Kim still managed to look as picture perfect as ever in the shot, taken in her bathroom.
In a previous interview, Kim said that she doesn't like to rely too much on make-up to look good.

'As much as it’s fun to glam up, the most important thing is to be comfortable in your own skin- with or without make-up.'

Kim's sexy dressed-down photo came after she spent the evening with sisters Kendall, Kylie and Khloe.
