As Lamar Odom lies unconscious in a Las Vegas hospital after a suspected drug overdose, According to RadarOnline.com his ex and baby mama, Liza Morales, is on her way to the scene and ready for a big showdown with Khloe Kardashian.

Why? Liza said it's very upsetting when she heard that Khloe took Camera crew to the Lamar Hospital bedside, plus:

 “She is fuming that Khloe, Kim, and Kris are all at Lamar’s bedside,” the source said. “Where have they been for the past year? All Kardashians have ever done is bring drama into Lamar’s life. And of course, Khloe has been using Lamar as her storyline for the past season of Keeping Up With The Kardashians,” the insider continued. “There was absolutely no reason to do it as Lamar hadn’t appeared on it for years, only phone calls with Khloe. She’s so angry, according to the insider, “Liza will toss Khloe out of the room, if she’s able! Lamar’s children and Liza are his family, not the Kardashians. Khloe had given up on the marriage and moved on. She doesn’t now get to play the concerned wife at Lamar’s side!”

 According to an insider, “Liza immediately began making arrangements to fly to Las Vegas from New York City with their two children, Destiny and Lamar Jr., to be by Lamar’s side.” “They are expected to arrive at Sunrise Hospital on Wednesday afternoon,” the source said. “His kids are old enough to understand what is going on, and Liza just wants to get to the hospital. It makes Liza and the kids furious that the media is referring to Lamar as Khloe’s ex. He is so much more than that: accomplished professional basketball player, father, and son. He was somebody before he met Khloe and the public needs to remember that.”

Lamar, 35, had been drinking and popping herbal Viagra pills at the brothel before the medical crisis.
