Khloe Kardashian has hit back after her husband was accused of failing to donate money raised through his charity to cancer research.

The 28-year-old reality TV star has insisted that Lamar Odom personally donated more than 90% of the money raised by his organisation Cathy's Kids and that all of the money was used for its intended purposes.

In a message on her official website on Tuesday (02.04.13), Khloe wrote: ''It is unfortunate that my husband has been the target of an attack on athletes' charities, although he has personally contributed approximately $2.2 million to his foundation, Cathy's Kids, to fulfil its charitable purposes that include helping underprivileged inner-city youth.

''The millions of dollars personally contributed by Lamar constituted more than 90% of the money raised by the foundation. All of the funds donated by Lamar and the other contributions to Cathy's Kids were used for one of the foundation's intended charitable purposes. Not one penny went to help Lamar personally or any member of his family. No charitable funds were misused, and the IRS has repeatedly given Cathy's Kids a clean bill of health, confirming that there were no improprieties.

''Cathy's Kids was formed with several purposes in mind, including benefitting underprivileged youth and cancer research. A decision was ultimately made that the charity should focus on one of those purposes -- to help enrich the lives of underprivileged inner-city youth. It accomplished that goal. Cathy's Kids helped fund multiple AAU basketball teams providing underprivileged youth with opportunities enriching their lives, providing financial support for coaching and travel to tournaments, helping inner-city youth on a path toward success and leading many participants to go on to college.''

The LA Clippers star - who has been married to Khloe for three years - was accused on Monday (01.04.13) of failing to donate any of money raised through his foundation, which was named after his late mother Cathy, who died from cancer when he was 12, to help fight cancer.

ESPN's 'Outside the Lines' claimed there is no evidence that any of the $2.2 million raised through Lamar's organisation, which was set up with the intention of raising money for underprivileged kids in New York and LA and for cancer research, went to a cancer charity and claimed that $900,000 was missing.
