Caitlyn Jenner has rented a $400,000 Lamborghini

Caitlyn - who was known as Bruce Jenner before her transition - is a fan of high-speed sports and loves racing ATVs and motorcycles.

Meanwhile, Caitlyn, 65, was recently slammed by one of the drivers in her fatal car accident.

The Olympian was involved in a crash on Malibu's Pacific Coast Highway in February that killed Kim Howe, and Jessica Steindorff, the driver of a Prius involved in the pile-up, has called on her to "do the right thing".

She also hit out at the decision to award Caitlyn the Arthur Ashe Courage Award at the 2015 ESPYs last week.

The 29-year-old talent manager - who was a guest at the ceremony - told 'Entertainment Tonight': "I find it difficult to understand how the culture we live in can honour a person who is responsible for taking a life and injuring several others with both an award and a reality show.

"For an individual who is such a positive role model in many aspects of her life, Caitlyn has failed to do the right thing and take responsibility for her actions.

"I would hope that someone who seems to greatly value the importance of human existence would be more sensitive to the fact that she ended another person's life. Sadly we are living in a tabloid society."

Jessica spoke out a month after she filed a personal injury lawsuit against Caitlyn, in which she claimed the 'I Am Cait' star caused the collision by driving "negligently, carelessly, recklessly and wantonly".

She is seeking more than $25,000 in damages.

Caitlyn has not faced criminal charges over the accident, which the Los Angeles County Sheriff's Department continue to investigate.
