It’s been a very tough couple of weeks for Khloé Kardashian and her estranged husband, Lamar Odom.

One week after their friend Jamie Sangouthai succumbed to a flesh-eating-disease, which was most likely caused by his chronic drug use, the former couple suffered another devastating blow when close pal Bobby Heyward passed away from what appears to be a drug overdose.

And now a new report claims the Keeping Up With the Kardashians star, 30, is “inconsolable” following the latest loss.

Bobby and Lamar were very close friends.

“Everyone who knew Bobby is still in shock and grief,” a source who knows both Khloé and Bobby tells Radar Online.

“No one is leaving Khloe’s side right now because she needs a lot of support to get through this, but right now she is inconsolable.”

It’s been especially hard on the reality star because of the close bond she had with Bobby.

“Khloé was not as close to Jamie, but she was really good friends with Bobby,” says the source. “She is being silent on the matter because she doesn’t believe it was intentional.”

Bobby was just 30-years-old when he was found dead on June 22 — one week after Jamie passed away on June 14. A cause of death has not yet been confirmed, though LA County coroner Ed Winter said that law enforcement officials believe it’s an overdose.

In the days leading up to his untimely death, Bobby had taken to Instagram to honor his late friend.
