Khloé Kardashian is "terrified" about losing Lamar Odom.

A source shared: "Nobody can really understand Khloé's motivation for fight over the money. It's been so long now it seems bizarre that she's still out for revenge.

"And she and her family have more than enough money to keep her living in luxury for the rest of her life. It's clearly because she wants to keep him close. She feels like she will never hear from Lamar again if she divorces him. Losing him forever terrifies her."

The 30-year-old television personality - who tied the knot with Lamar, 35, in 2009 - is believed to be "fighting" with him over money he reportedly emptied from one of their joint bank accounts.

The insider added to HollywoodLife.com: "Khloé and Lamar aren't divorced because Khloé is still fighting him for money. She feels he was the one who screwed her over and he should pay her millions.

"They are still fighting over a secret joint bank account they had which Lamar emptied when they separated. He's spent all that money and Khloé wants it back. Not only that but she thinks he should pay her half the value of his house in Florida."
