*Khloé Kardashian is said to be considering a restraining order against her estranged husband, Lamar Odom, to stop his alleged harassment.

“He’s totally lost it, calling her every name under the sun and yelling at her for breaking promises she made to him on his death bed,” a source told RadarOnline. “It’s pretty vicious … [Odom] has been bombarding her with bitter texts and drunken rambling messages that are starting to scare her.”

The insider added, “She’s now considering a restraining order against him because he’s been threatening all kinds of crazy things, from spilling all her secrets to hoping she drops dead.”

Kardashian, 35, recently re-filed for divorce from Odom, 36, following his recovery from an overdose at a brothel in October 2015. Recent reports claim Odom’s friends are worried that he’s using drugs again.

“He’s broke and desperate and she’s his last remaining source of cash,” the source told Radar. “He’s so out of control he’s capable of anything.”
