"Khloe, Kourtney and Kim have really been distancing themselves from Brody because of his girlfriend, Jayde [Nicole]," the insider says. "After her bar fight with their friend Joe Francis, they realized she's bad news, but they can't get Brody to see it."
"They’re concerned because Brody has developed an anger management problem," the source says. "It’s almost like she brings out the worst in him, so the girls are steering clear of their stepbrother until he ditches Jayde."
