?Khloe Kardashian thinks it is important to "make time" for her husband.

The reality TV star - who married basketball player Lamar Odom in 2009 after just 30 days of dating - believes it is easy for couples to drift apart if they don't make effort to keep the union fresh.

She said: "Without two people trying, there is no marriage.

"With our busy schedules we have to make time for each other. Once you forget to do the little things, it's easy to grow apart."

Khloe is often questioned as to why she and Lamar have not had children yet, and though she admits she felt pressured by the constant speculation, she is in no rush to start a family.

She said: "At first it put pressure on me. Now I'm letting nature take its course. I'm more flattered by the interest than anything else."

Despite her wealth and fame, Khloe insists the only thing that makes her feel successful is the fact she has a close relationship with her family.

She told Britain's HELLO! magazine: "Being famous doesn't necessarily mean you are successful. I'm very successful because I have a phenomenal family."
