Lamar Odom's ex-girlfriend, Liza Morales, and their two children, have now arrived in Las Vegas to be with the ailing 35-year-old basketball star.

ET can confirm that Morales as well as Odom's daughter, Destiny, and his son, Lamar Jr., are in Vegas after traveling from New York City. The family also arrived with Lamar's aunt, JaNean.


The four join the Kardashian-Jenner family -- Khloe, Kim, Kourtney, Kendall, Kylie, and Kris -- who are all currently in Vegas as Lamar remains in critical condition.

Despite reports that 31-year-old Khloe paid for Lamar's ex-girlfriend and children to fly out to Vegas, a source tells ET this is not the case.

On Wednesday, Destiny tweeted out a childhood photo of her and her father with the heartbreaking message, "Please don't leave us."

In 2013, Morales opened up about her relationship with Lamar, specifically, how it changed after the two lost their son Jayden in 2006 when he was 6 months old to Sudden Infant Death Syndrome.

"Lamar and I never really talked about our loss, which I know wasn't healthy and also meant our relationship would never last. It couldn't," she told The Daily Beast. "We kept things cordial for the children's sake after the breakup, but that changed when he married Khloe. Now we only communicate through third parties and lawyers, which I regret deeply since it is exactly what we each experienced as children and said we wouldn't do to our kids."

Meanwhile, Kanye West was expected to arrive in Vegas on Wednesday night, though he hasn't been spotted at the hospital. There's also been no sign of 28-year-old Rob Kardashian, though the press-shy Rob -- who had a notably close relationship with Lamar on Keeping Up With the Kardashians -- Instagrammed on Wednesday that he was "praying nonstop" for his "brother."

As for Scott Disick, the 32-year-old reality star has checked into a drug and alcohol rehab center for treatment, a source confirmed to ET on Wednesday. When news broke of Lamar's hospitalization on Tuesday, he cryptically Instagrammed, "Never give up."

Kylie Jenner Instagrammed a picture of her and Lamar on Thursday, writing, "Let's dance again together soon. Prayers up for Lamar please."

ET was told on Wednesday that Lamar remains in critical condition after he was found unconscious at the Love Ranch brothel in Crystal, Nevada, and that he has also been placed on dialysis after starting to experience kidney failure. But according to our source, he has had a few encouraging improvements, including briefly fluttering his eyes.

Audio from the 911 call released by the Nye County Sheriff’s Office on Wednesday alleges that Lamar had used cocaine, as well as an "enhancement" supplement, consistent with Love Ranch owner Dennis Hof’s claims that the former basketball star had taken an herbal Viagra substitute while staying at the brothel.
