Talking to your brother-in-law about his sex life is the stuff of nightmares. The only thing worse is talking to him about sex he’s having with someone other than his wife.

Luckily, the world is full of brave bros like Rob Kardashian, who are man enough for the task.

RadarOnline reports that after growing sick of hearing reports that brother-in-law Lamar Odom was cheating on his sister, Khloe Kardashian, Rob decided to have a mano a mano with the NBA star.

“Rob confronted Lamar and it got heated very, very quickly. Rob and Lamar have been close since he came into Khloe’s life,” says a source for the website.

“When Rob asked Lamar point blank if he had cheated on Khloe with criminal defense attorney Polina Polonsky, he refused to answer the question. Rob grew angrier that Lamar didn’t respond, and he ended up just leaving the house. A lot of people bash Rob, but he truly has his sister’s back, and is very protective of her.”

The source claims that, upon finding out about Lamar’s affair with Polina, Khloe kicked her hubby out of the house, although she has continued to speak with him daily and visit the hotel where he’s been living. In his absence, Rob has stepped in to comfort his sister.

“Rob has been continuing to stay with Khloe, and has been a big source of support for her at this very difficult time,” says the source.

Do you respect Rob’s decision, or should he mind his own business?
