Rob Kardashian "truly has his sister's back" in the wake of rumors husband Lamar Odom has cheated on Khloé.
Lamar's marriage to Khloé Kardashian has been rocked by cheating scandals of late - with two women coming forward to say they had affairs with the basketball star.
Younger brother Rob - who has lived with the couple on and off in their Californian home - has forged a brotherly bond with Lamar since he married his sister in 2009 and apparently became incensed when the rumours emerged.
“Rob confronted Lamar and it got heated very, very quickly. Rob and Lamar have been close since he came into Khloé's life,” a family insider told Radar Online.
“When Rob asked Lamar point blank if he had cheated on Khloé with criminal defence 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.”
Jennifer Richardson, 29, came forward last month maintaining that the Los Angeles Clippers player had been cheating on his wife Khloé for around a year.
Lawyer Polina has also claimed that she enjoyed sexual relations with the sportsman over a six-week period.
Since the second claims emerged, Lamar has reportedly been kicked out of their marital home. Rob is said to have been a real comfort to his sibling.
“Rob has been continuing to stay with Khloé, and has been a big source of support for her at this very difficult time," the insider added.
Polina insists she has passed a polygraph test to back up her story, while Khloé is yet to speak publicly about the claims.
