Kim Kardashian's Marriage Lasts Just 72 Days

US reality TV star Kim Kardashian has filed for divorce from basketball player Kris Humphries after 10 weeks of marriage.

The couple were wed in a star-studded, TV ceremony in August, but the "Keeping Up With The Kardashians" star said the couple were now splitting due to "irreconcilable differences".

"I hope everyone understands this was not an easy decision," Kardashian said in a statement.

"I had hoped this marriage was forever but sometimes things don't work out as planned."

Documents filed with a US court show the couple signed a prenuptial agreement that will dictate how they divide up their assets.

They also revealed that 31-year-old Kardashian is requesting both sides pay their own legal costs and that Humphries' rights to spousal support are rejected.

Kardashian said she and Humphries, 26, "remain friends and wish each other the best."

However, Humphries told celebrity news website TMZ he was "devastated" to learn his bride had filed for divorce and is "willing to do whatever it takes to make it work".

"ThingsLongerThanKimsMarriage" quickly becoming a trending topic on the social networking site Twitter.

The couple were wed at a lavish private estate near Santa Barbara, California on August 20.

It was the first marriage for Humphries, who played for the NBA's New Jersey Nets but is now a free agent, and the second for Kardashian, who was married to music producer Damon Thomas from 2000 to 2004.

The pair began dating late last year and announced their engagement in May, after Humphries proposed on bended knee with a 20.5-carat ring and spelling out "Will you marry me?" in rose petals.

Their marriage was the subject of a two-part TV special which drew more than 10 million viewers in the US.
