Although Khloe rushed to her estranged husband's side and helped nurse him back to health when he overdosed at a Nevada brothel last year, she filed for divorce for a second time in May and they are no longer in close contact.

A source told Entertainment Tonight: "Lamar is out of her life completely. No animosity there - she still cares about him, she still wants him to be safe, but it's over."

Khloe, 32, recently started dating 25-year-old basketball player Tristan Thompson and could not be happier.

An insider said: "They're taking it slow, day by day, but are having so much fun together. It's still the honeymoon stages and they both have a huge crush on each other.

"He's the nicest, sweetest guy, 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. He's close friends with [his Cleveland Cavaliers teammate] LeBron [James] and a couple of his teammates.

"She's very happy but taking it slow and not rushing into anything."

Meanwhile, Khloe's mother Kris Jenner recently gave Tristan the seal of approval and gushed that he and Khloe are "really cute" together.

She said: "They are really cute. You know, she's having a good time. He seems like a really nice guy."

When asked what makes them work, Kris replied: "I don't know! I think just with any relationship, just in life, I think it's about chemistry and about values. You know, about how two people get along, so...you know how that goes!"
