The 27-year-old reality TV star married the basketball player in 2009 just 30 days after the couple started dating, and she was confident their relationship would last despite being surprised that her nuptials came around so quickly.
She said: ''I knew with every ounce of my body. Three days in, I just knew.
''If you'd asked me a month before I got married, I would never have said, 'I'll be married in a month.' ''
Despite rushing into their wedding, Khloe is in no hurry to start a family with Lamar, but she is keen to have children with the 32-year-old sportsman at some point in the future.
She added: ''Everyone makes it seem like I want [kids] right this second and I'm desperate, but I'm really not.
''I do want children, but I'm only 27. I was never the girl thinking, 'By the time I'm 25, I wanna have kids.'
