“Rob is willing to do whatever it takes to help Lamar recover,” says an insider. “If that means donating a kidney then so be it, Rob has a big heart and he's willing to step up to help his friend.”

Although it's still unclear whether Lamar, 35, and Rob, 28, have compatible kidneys.

The boys have been close since Lamar started dating Khloe, 31, in 2009 - and Rob even lived with his sister and the professional athlete before the pair became estranged.

What's more, after Lamar was found unconscious at a brothel in Las Vegas earlier this month following a four day drug bender, Rob took to Instagram to offer support.

"Praying nonstop for my brother!!" he captioned on old picture with the former NBA star.
