Khloe Kardashian has offered her older sister Kim some wedding advice before upcoming nuptials to Kris Humphries tomorrow (August 20).

The 'Keeping Up With The Kardashians' star will marry the NBA star in an exclusive ceremony in Montecito, California, that will be aired in a TV special later this year.

Khloe held a similar event when she married LA Lakers star Lamar Odom in September 2009, and she insisted that Kim will have to relax on her big day and not be concerned about everything running smoothly.

In an interview with US Weekly, the 27-year-old said: "It's not about having everything perfect! "At some point in your wedding, take your husband in a corner and just be quiet and look and enjoy the whole presence of it. And just look and enjoy because it goes so fast... it's amazing."

Khloe also offered Kim some relationship advice for when they are married, she said: "No two relationships are the same. Keep yours to yourself because everyone will have an opinion. They have no idea what goes on behind closed doors."
