Nearly a month after [article id="1673430"]Kim Kardashian filed for divorce[/article] from Kris Humphries, the NBA star is firing back, seeking an annulment to erase his brief 72-day marriage to the reality star on the grounds of fraud.

Under California law, an annulment will be granted only if the court finds that there was no validity to the marriage. In his Superior Court filing, Humphries checked the boxes marked "nullity of voidable marriage," citing "fraud" as the basis for their split.

If Humphries is denied an annulment, he is seeking legal separation, which means the former couple could avoid all divorce proceedings. Back in October, Humphries released a statement, saying he was committed to working on repairing his short-lived marriage. "I love my wife and am devastated to learn she filed for divorce," he told People magazine at the time. "I'm committed to this marriage and everything this covenant represents and I'm willing to do whatever it takes to make it work."

On October 31, Kardashian filed for divorce, citing "irreconcilable differences." "After careful consideration, I have decided to end my marriage. I hope everyone understands this was not an easy decision," [article id="1673465"]Kardashian said in a statement[/article]. "I had hoped this marriage was forever but sometimes things don't work out as planned. We remain friends and wish each other the best."

Court papers released online state that Kardashian requested the court uphold the prenuptial agreement the two signed before the wedding, which guarantees that the reality star will keep all money earned during their marriage.

Kardashian and Humphries married on August 20 in a lavish $10 million affair that was captured by E! cameras and aired in a two-day television special. Their relationship is currently being played out on this season of "Kourtney and Kim Take New York."

The news comes on the same day as Kim's sister, [article id="1675120"]Kourtney Kardashian, revealed that she is pregnant[/article] with her second child with boyfriend Scott Disick.
