The outpouring of love and support for Lamar Odom since his hospitalization Tuesday continues to grow. Just hours after learning of his condition, estranged wife Khloé Kardashian and former mother and sister-in-law Kris Jenner and Kim Kardashian West jetted to Las Vegas to be by his side and have not left. Now, another member of the celebrity family is joining them in Odom's hospital room.

According to E! Online, Caitlyn Jenner has flown to Las Vegas to be with the 35-year-old former Los Angeles Lakers star and her family. She is said to have gone directly from visiting her mother, Esther, to the hospital. Esther Jenner, 89, is recovering from two broken hips. Caitlyn, 65, has not commented on Odom's condition, nor has she been seen in public at the hospital.

Kris Jenner, 59, was photographed outside Odom's hospital room Wednesday. She appeared visibly upset, holding her head as she walked through a parking lot. As was reported, Khloé, 30, is said to be sticking close by her former better half's side. Sources say she is distraught at the thought of losing him.

Odom was rushed to the hospital Tuesday after being found unconscious inside Love South Ranch in Pahrump, Nevada. He is currently on life support and in a coma after having suffered a stroke. Doctors are said to have found traces of cocaine in his system as well as track marks on his arms. Other sources told E! Odom had "virtually every drug imaginable" in his body. It has been reported that he is being treated for an overdose, and that "it doesn't look good." 

It remains unclear what events lead up to Odom's collapse. Dennis Hof, owner of Love Ranch South, said the former "Khloé and Lamar" star was at the legal brothel to get some "time to himself." Other sources said Odom seemed "chill" upon arrival, but added that they noticed a change in his demeanor after he received a phone call Sunday about the Season 10 finale of "Keeping Up With the Kardashians." He is said to have been angry, claiming he was portrayed unfairly in the episode during which he and Khloé communicated via telephone several times. The sources added that Odom stayed upset until the moment he was found unconscious.

The Kardashian family has not released a statement regarding Odom's condition. They, along with the rest of his family and friends, are said to be holding out hope that he will recover.
