Khloé Kardashian admits she will never get over Lamar Odom.

The 30-year-old reality TV star, who recently started dating rapper French Montana after filing for divorce from her estranged husband of four years in December, amid rumours he cheated on her and was battling a drug addiction, says their split will weigh on her for the rest of her life.

In a clip from Sunday's (03.08.14) episode of 'Keeping Up with the Kardashians,' the brunette beauty tells her step-brother, Brandon Jenner: ''Lamar stuff will weigh on me for the rest of my life. The marriage didn't work out not because of me, it wasn't what I wanted. So for the rest of my life I'm going to deal with that, worry about him, think about him and want just to protect him.''

The E! star also addresses rumours that the basketball star cheated on her with multiple women, saying: ''He got so sloppy and started messing with all those girls, and all those girls want to do is their 10 seconds of fame.''

The scenes were filmed in Thailand in April just weeks after Khloé began dating French.

But their romance is still going strong and she recently gushed: ''He is just funny. He's light and it's easy. That's what I need right now.

''It's fun. I like how he's always happy. Smiles are infectious. They're contagious. I like that... I just want more positivity in life.''
