Khloe Kardashian is bracing for the inevitable as she remains by the side of her estranged husband, Lamar Odom. Odom was found unconscious at a Nevada brothel on Tuesday, and he's remained at Sunrise Hospital on life support ever since.

"It's hard for Khloé. He is on his last leg," a source tells People. "Everyone wanted to hope for the best, but nothing has changed. Now they are preparing for the worst. Khloe has always loved him. And that has never changed and if he didn't have issues, they would be together. She's devastated."

Kardashian immediately flew to Las Vegas on Tuesday, and she was joined by sister Kim and mom Kris Jenner. The following day the trio was joined by Kourtney Kardashian, Kendall Jenner and Kylie Jenner. On Thursday a message posted on the family's websites reads, "As a family, we've decided to hold off on publishing content across our apps while we continue to support and pray for Lamar. Thank you for your kindness and understanding during this difficult time."

Odom's two children, Destiny, 17, and Lamar Jr., 13, also broke their silence. "Thanks for your outpouring of prayers and support for our dad. We are here with our family and friends," they said in a statement to CNN. "We appreciate everyone respecting our privacy at this time. We ask for your continued prayers."

Odom's father Joe is also at the hospital, and Khloe flew the former NBA star's kids and ex-girlfriend Liza Morales out from New York so they could be with Odom too.
