Rob Kardashian has not been spotted in public much this 2015 as compared in the past years. But after Lamar Odom's hospitalization, he has purportedly set aside his apparent hiding to be with his brother.

As reported by People, the "Keeping Up With The Kardashians" star reportedly was seen in Los Angeles recently as his brother has been apparently transferred to Cedars-Sinai a week ago. In the picture that many entertainment websites published, Rob was said to have been seen driving Khloe Kardashian's car.

Rob Kardashian also reportedly has been somehow instrumental in Lamar Odom's recovery for the remainder of 2015. According to a report on Hollywood Life, Khloe Kardashian has been reportedly spoiling the former NBA star with help from Rob's sock line.

"Lamar looks like he's about to go skiing," an insider told the source above. "He's all bundled up because he's freezing cold in his hospital room."

"He's got Rob Kardashian's socks from his Arthur George line on his feet," the insider added. "He absolutely loves them. His favorite pair are the black and whites ones that have 'BIG' written on one sole and 'Daddy' on the other."

A week ago, the younger "Keeping Up With The Kardashians" star took to Instagram to express himself after news that Odom has been hospitalized.

"Praying nonstop for my brother!!" the "Keeping Up With The Kardashians" star wrote along with an old picture with the former NBA star.

The younger Kardashian has been quite close to Odom prior to the former NBA star's falling out with his sister. As told by Inquisitr, Rob got close to Odom and has called him his "brother" when he still lived with Khloe Kardashian and Odom. He also reportedly was affected by their split.

But with Lamar Odom's hospitalization and purported reconciliation with Khloe Kardashian, Rob Kardashian may seemingly bounce back as well. Khloe and Lamar's divorce was reportedly on hold according to CNN amid his recovery following a coma from an apparent drug overdose.

"This is a very delicate and difficult time for both Lamar and Khloe, and the most sensible thing to do at such a time is not make any big moves and put everything on hold," an insider told the source above. "So that's what she is doing."
