Lamar Odom's dad thinks his son is 'better off without' Khloe Kardashian.

The 33-year-old basketball player wed the 29-year-old reality TV star in September 2009 but his father, Joe, wants them to end their four-year marriage in light of allegations Lamar has been cheating and is a drug user as Joe believes these accusations have come from image conscious Khloe and her famous family.

Joe told heat magazine: 'They brought him down. He would be better off without them. I think the best thing for him would be to have a clean break and divorce Khloe. She's been talking trash about my son, saying he's on drugs and stuff like that. I don't think she cares about Lamar, she just cares about their image and money.'

He added: 'I wish he had never got married to Khloe. She's controlling. Those Kardashian women all are. In public she's nice, but if you see her personally you see the real person. The mother's like that, too.'

He was also furious about elder sister Kim's - who is in a relationship with rapper Kanye West - reaction to reports of Lamar's drug abuse and hit out at her while referring to the sex tape she made with former boyfriend Ray J which was leaked in 2007, saying: 'I heard Kim said they don't have crackheads in their family. That p***ed me off. Look at where she came from. We don't want porno stars in our family.'

This comes as Khloe has dropped the her husband's surname from her Instagram account, now solely using her maiden name.
