The former glamour model took to her Twitter account after a high street bike shop refused to donate a bike to her so she can take part in a 300m Sport Relief bike ride.
The star wrote: ‘Thanks Halfords for saying your donate a bike for me for sports relief to raise money and my 300mile ride for charity and now saying NO (sic).’
According to the tweets, Katie had been promised a free bike for the Sports Relief event but the high street chain had failed to follow through.
Katie then took matters into her own hands and appealed to other brands, asking if any other companies would be willing to donate a bike.
She tweeted: ‘If there is any other company who want to donate a bike I can auction and ride in sports relief and 300 mile for charity tweet me x’
Katie has earned a fortune through her modelling career and continues to earn millions thanks to her business ventures.
The star regularly raises money for charity and she has taken part in numerous charity events to raise funds for good causes.
