More of the Kardashian-Jenner family is starting to arrive in Las Vegas to visit Lamar Odom in the hospital.
Kourtney Kardashian landed around 3 p.m. PT after taking a private jet from Van Nuys, California. Her younger sister, Kendall Jenner, touched down about an hour later.
Lamar's ex-girlfriend, Liza Morales, and one of their two children, 13-year old Lamar Jr., are en route to Las Vegas from New York City along with his aunt, JaNean, sources confirm. Lamar and Liza also have a 17-year-old daughter, Destiny, but it is unknown if she has already flown out to Vegas.
Kardashian matriarch Kris Jenner has been seen at the hospital, as have Odom's father, Joe Odom, his former Lakers teammate Kobe Bryant, and Jesse Jackson. Kim's husband, Kanye West, is expected to arrive soon.
A source close to the Kardashian-Jenner family -- who are not filming their reality show, Keeping Up With the Kardashians, at this time -- say they are "devastated" and "praying for a miracle to happen."
The 35-year-old basketball player was hospitalized on Tuesday afternoon after being found unconscious at Love Ranch, a legal brothel about 80 miles northwest of Las Vegas in Crystal, Nevada. He was initially brought to Desert View Hospital in nearby Pahrump before being transported to Sunrise.
Lamar reportedly suffered a heart attack Tuesday night and was placed into a medically induced coma. While his condition has improved, a source tells ET that his situation "is still dire."
Early Wednesday, Liza shared a quote from Tupac Shakur on her Twitter page that alludes to Lamar's current hospitalization.
Kendall also tweeted on Wednesday, sending a heartbreaking plea to Lamar.
