How sweet...Rob Kardashain is ready to donate his kidney to Lamar Odom if the need arises

According to daily mail, Rob Kardashian has offered his kidney to brother-in-law and close friend Lamar Odom should the seriously ill former NBA star need a transplant.

 Khloe Kardashain's brother stepped up with the generous offer after it emerged Odom may need a new kidney as his medical treatment continues in Los Angeles.

It's unclear whether Odom and Rob are a compatible match for a kidney transplant, but Rob is willing to undergo medical tests to find out, sources reveal.
