As for Khloe's complicated relationship with Lamar, the source says it's now pretty much non-existent.
Khloe filed for divorce from Lamar for the second time in May.
"He comes from a very strong family and has a tight circle of close friends.
He really isn't into the 'celeb scene' and does his own thing.
It’s not even in our brains thinking about us as a couple or having a now.” Of Lamar, Khloe also said “I loved him always, and I will always love him.” Most observers therefore assumed that Khloe’s pre-existing relationship with current Houston Rocket James Harden was over and done with.
