The 32-year-old sportsman - who stars alongside the popular 27-year-old sister of Kim and Kourtney in various shows - is keen to move on with his life away from the cameras, but his wife is unsure if it is a good move.
A source told HollywoodLife.com: ''Lamar wants out of the reality TV limelight, but Khloe is convinced that if Lamar doesn't continue being on TV with her, there would be no Khloe.
''The whole reason Khloe has become so popular is because of her marriage to Lamar. She obviously doesn't want Lamar to be unhappy, but she knows that all the drama makes for good TV. Fame is Khloe's number one priority. Unfortunately, this is what she has been taught.''
His thoughts about the format - which sees them followed in all aspects of their life - have put a strain on their relationship, but as yet no permanent decision has been made.
He said: ''Of course, Lamar is not obligated to star in any more Kardashian reality shows, but Khloe would be devastated if he said no.
''Khloe may end up having to choose between her marriage or reality TV and fame.''
