Rob Kardashian was one of the closest people to Lamar Odom for many years. So, as the former Los Angeles Laker remains in a coma with his organs reportedly failing, Rob Kardashian and his family are at Odom's side, praying he will soon come to.

Last night, October 14, Rob Kardashian surfaced on Instagram, where he posted a message to fans, which read, "Praying nonstop for my Brother!!"

Rob Kardashian's mother, Kris Jenner, also shared a message on Instagram last night. In the caption of a photo of Odom playing basketball, Jenner wrote, "Please pray for Lamar #ourfighter."

Numerous athlete and celebrities have been flooding social media with comments and well wishes to Odom and his family, including Kris Humphries, the former husband of Rob Kardashian's sister, Kim Kardashian. In his message to fans on Twitter, Humphries said, "Everyone please pray for @RealLamarOdom to make it through this. Great player, even better person!"

Rob Kardashian is rarely spotted publicly due to his ongoing struggles with weight and depression, but after learning of Odom's hospitalization on Tuesday, October 13, Rob Kardashian was said to have come out of hiding to travel to Las Vegas to be at his side. According to a report by the Daily Mail Online, Rob Kardashian was joined by Scott Disick, as well as many others, who have traveled to the Sunrise Hospital in Las Vegas, where Odom is currently receiving treatment.

Rob Kardashian's "brother," Odom, as he continues to call him, despite his split from Rob Kardashian's sister, Khloe, was found unconscious earlier this week by two women at Dennis Hof's Love Ranch South, where he had reportedly been partying since Saturday. In a TMZ report, it was revealed that Odom was declared to be in a coma by 11 p.m. Pacific Time, with several of his organs, including his kidneys, heart, and lungs, failing.

Rob Kardashian has also been in the news lately due to his ex-girlfriend Adrienne Bailon's comments about their rumored reconciliation. During an event earlier this month, via Us Weekly, Bailon claimed Rob Kardashian was a "great guy," and said she wished him well, but shot down rumors about them getting back together.

As for Rob Kardashian's own struggles, the reality star and sock designer was recently linked to an allegedly dangerous diet. As he continues to fight back against weight gain, Rob Kardashian reportedly took on a diet which was believed to put him at risk for a heart attack. On week ago, Radar Online reported news of Rob Kardashian's potential health risk, claiming he had taken on the "heart attack diet."

Below is what a source told the site about Rob Kardashian's alleged diet.

"[Rob Kardashian]'s been yo-yo dieting for years, but the constant stopping and starting of it all is taking a real toll on his health. He's dehydrated all the time, gets palpitations and it's putting a lot of stress on his heart while his body goes into starvation mode. He should be taking the same time to lose this weight as he did to put it on, but now that he's seeing results, you just can't stop him."
Rob Kardashian has not yet confirmed or denied being at the hospital with Odom, nor have any photos of him surfaced at the hospital. His mother, Kris Jenner, on the other hand, was recently spotted with her hand on her head outside of the facility.
