Lamar shared his feelings about his ex-wife Khloe Kardashian in a sneak peek of Celebrity Big Brother.

The retired NBA player let out his emotions to former American idol contestant Todrick Hall about the one he loved dearly. An exclusive sneak peek of Celebrity Big Brother catches Odom saying he had a dream about the Keeping Up with the Kardashians actress,

"I had some good dreams last night. I dreamt my ex-wife last night." -Odom
"Who's your ex-wife?" -Hall
"You don't know her?" -Odom
"How many ex-wives have you had?" -Hall
"Just one." -Odom
"Oh, so Khloe." -Hall

In the clip, you can see Odom is visibly upset not only because he misses her but because of his past that's led him to this chat with Hall.

Odom married Kardashian back in 2009 and they created the show Khloe and Lamar in 2011. The show only lasted two seasons, which was then followed by Khloe filing for a divorce in 2013. Lamar suffered from a crack cocaine addiction two years later and was put into a coma in 2015 after he was found in a Nevada brothel.

Having heard of this news, Khloe removed the divorce files so she could aid Lamar through those troubling times. He was able to regain consciousness, but a year later saw Khloe continue to file the divorce and finalize it.

Odom continued the conversation with Hall, saying

"I miss her so much. I wish I could take that time back." -Odom
"How long were y'all married?" -Hall
"4 years...I miss her so much!" -Odom

You can watch Odom on Celebrity Big Brother, premiering February 2nd on CBS.
