"[Khloe] has to be careful," Kharbouch tells Life & Style magazine. "Things are not what they seem."
Rumors of a relationship between Montana and Kardashian are flying as the two continue to be spotted in each other's company. The pair were seen together several times last weekend, and recently attended a party in West Hollywood. Kardashian filed for divorce from husband Lamar Odom last December, but both she and Montana are still technically married.
Kharbouch and Montana married in 2007 and have one child, Kruz, who was born in 2009. She says that she and Montana "worked together to put him where he is," but claims he left her and their son after he became successful.
"As soon as he popped, it was as if Kruz and I didn't exist," Kharbouch says. "He practically abandoned us. Sometimes we won't hear from him for two to three months."
A different source tells the magazine that the Kardashian family is worried about the rumored relationship. "They think she's headed down the same path she did with Lamar," the person says.
