In the eerie caption, Hayward wrote, "#RIP To my big brother Jamie who always brought light into any room he walked into and laughter as well at all times J you will always be missed. Family for life. #BandOfBrothers #tbt."

As RadarOnline.com previously reported just after Heyward's death, those close to Odom were urging him to get into rehab -- over fears that the recent string of deaths would push him over the edge.

Although Odom's health condition appears dire after he was found unresponsive Tuesday at Dennis Hof's Love Ranch in Crystal, Nevada, his father Joe, as well as ex-wife Khloe Kardashian, sister Kim and mother Kris Jenner all rushed to the hospital to be by his side.

According to multiple reports, there were numerous drugs found in Odom's system when his body was discovered.
