As Khloe Kardashian’s estranged husband, Lamar Odom, lies in serious coma — which is obviously stressful enough — she at least has one less thing to worry about. Her boyfriend, James Harden, is totally supportive of her being at Lamar’s bedside in Las Vegas.

James Harden, 26, is totally a keeper. The Houston Rockets player told his girlfriend, Khloe Kardashian, 31, not to worry about him, but instead, spend as much time as needed with Lamar Odom, 35, who’s barely clinging onto life at Sunrise Hospital in Las Vegas. He’s more than fine with her putting her life on hold and sleeping on the floor in Lamar’s hospital room until he recovers. How very mature of him.

“James has told Khloe not to worry about him at all through this whole Lamar ordeal and she can take as much time as she needs to be with Lamar. James is focused on his upcoming season and current pre-season and doesn’t want to be in the way, but will be there for Khloe when she needs him. He sees the bigger picture and is very understanding,” a source tells HollywoodLife.com EXCLUSIVELY.

We can only imagine Khloe loves James so much more because of this. Obviously, her attention is on Lamar right now, but we hope she holds on to James — he’s super sweet.

“Times like this are when people show who they really are and James has complete compassion for Lamar and is shocked by the news that he’s in a hospital, clinging to life. He spoke to Khloe and absolutely encouraged her to be there for Lamar and his family during this time. He’s completely supportive of Khloe at this moment. He’s never heard Khloe sound so scared and nervous in his life after talking to her about this situation. She has been down right frantic. James knows exactly what Lamar means to her and supports her being at his bedside,” another source tells HollywoodLife.com EXCLUSIVELY.
