Khloe Kardashian, Lamar Odom Divorce Fight [UPDATE]: Rob Kardashian Confronts Lamar Over Cheating Scandal With Several Mistresses

Khloe Kardashian's brother, Rob Kardashian has gotten into an intense confrontation with Lamar Odom over his cheating scandal.

The only Kardashian man was always close to Odom throughout his years living with the couple and during his recent weight struggles where he confided in Odom about missing out on the family trip to Greece. According to RadarOnline source, Robert has defended his sister and approached his brother-in-law, "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."

Recently, Rob has been staying with his sister after she kicked Odom out of their mansion, "Rob has been continuing to stay with Khloe, and has been a big source of support for her at this very difficult time."

Khloe Kardashian and Lamar Odom's divorce is official after she posted a picture of her estranged husband's hotel room.

According to RadarOnline.com, Odom had moved into The Garden Inn Hilton in Calabasas, Calif., after the NBA star was allegedly kicked out of his luxurious mansion by his wife, Khloe after finding out about more of his rumored cheating ways.

According to X17online, Khloe went to visit Odom at his hotel for 20 minutes before leaving the establishment alone. As Khloe headed back to her mansion, Odom stayed at his rumored new residence. X17online's photographers claim:  "Khloe looked really upset when she went in and when she came out of the hotel after talking to Lamar. She was like a woman on a mission -- she wasn't looking too warm and fuzzy; she looked sick and tired of it all."

A family source confirmed to RadarOnline that the couple has separated, "He had been staying at the Hilton, but once photographers found out he was staying there, he moved to another location. Lamar isn't living under the same roof with Khloe right now. She knows he has been cheating on her and is absolutely devastated."
