Jamie Kah appears to rack up a line of white powder in shock photo

Images of horse racing champion Jamie Kah appearing to rack up a line of white powder have spread on social media, just one day after she announced she was returning to the sport.

Kah, 27, announced on Thursday she was back in the saddle and preparing to make a return to racing, three months on from a horror fall that resulted in a stint in hospital due to a brain bleed and memory loss. 

However, just a day later damning photos have been circulating within the racing industry on Whatsapp which appears to show Kah racking up a line of a white substance.

In one of the images, she is seen wearing a grey robe with manicured white nails, and her hand resting on her cheek as she smiles to camera.

The bombshell development comes just one day after she announced her racing return

News Corp reports that Kah is pictured with close friend and housemate Jacob Biddell, who is a greyhound trainer. He is seen pouting for the photo in a ribbed cream turtleneck jumper.

Another girl is pulling peace signs with her hands, with a grey plate placed on a marble kitchen table.

The second photo, appears to show Kah’s hand – with the same manicured nails and grey jumper – using a plastic card to split a mound of white powder on the plate that was seen in the first image.

There is also a little bag containing white powder and a vape next to the plate on the same marble kitchen top. 

Kah has yet to respond to news of the pictures’ publication and racing insiders have told the Herald Sun that she was unaware that she was being photographed while lining up the white substance. 

Daily Mail Australia has contacted Kah’s management for comment.
