He seems so sad!

Lamar Odom made an appearance on the Wendy Williams show today, and the basketball star discussed his overdose, his failed marriage to Khloe Kardashian, and much more. One thing we weren't expecting him to open up about? His fall out with Rob Kardashian!

The two were practically brothers, as the Arthur George sock designer lived with the NBA star and his sister for years before they split, but they don't keep in touch anymore.

"We were close. He has a child. I haven’t met his child yet or anything," he told the TV host. “I don’t know. I guess maybe it’s because I hurt his sister too much. I have no idea. If she was my sister, I would have a problem with me too," he added.

As for his desire to get back with his former wife? Although he initially wanted that after going to rehab and getting sober, he's now changed his mind. Not that he has much of a choice, as she's happily dating boyfriend Tristan Thompson.

"I say that with no offense to her, that would be the best for both of us. We have to keep our distance," he confessed.

We will always have a soft spot for Lam Lam!
