Kanye West is furious about the fact that girlfriend Kim Kardashian is still legally married to her ex Kris Humphries.

Though it's been more than one year since Kardashian filed for divorce, Humphries and his legal team have delayed the proceedings by seeking an annulment rather than a simple divorce settlement. Humphries claims the 72-day marriage was a fraud because Kardashian only married him for publicity.

A new report said West is angry because he is ready to marry Kardashian, but he can't do it until she is legally divorced.

"The only thing he wants to give Kim for Christmas, he can't. He wants her to be free from this," the source said. "It's been going on way too long and he hates this. ... You don't understand how much he despises [Kris Humphries]. He hates this dude with a passion."

In an effort to jumpstart progress on the divorce, Kardashian is now threatening to sue Humphries if he and his legal team don't take action to make the proceedings move along.

"She has instructed her lawyer, Laura Wasser, to give Kris and his lawyers an ultimatum: Settle now or she will sue," a source said, adding that a lawsuit could create a pile of attorney's fees for Humphries. "[They] could cost Kris millions."

Humphries and his team of attorneys have said they don't want to delay an official divorce, but they need time to build a case. The NBA player also wants Kardashian to return the diamond engagement ring he gave her.

But the reality star is prepared to cite the ways Humphries has damaged her career and include that in her suit.

"Kim will launch a counterattack for defamation of character," the insider added. "You can't put a price tag on what Kris has cost her."

Kardashian's divorce attorney said in court Thursday that her client wants to move on from the 72-day marriage with Humphries, but that has become impossible as the basketball player and his legal team are still not ready to move forward with a trial, according to a report from USA Today.

"Ms. Kardashian is now handcuffed to Mr. Humphries," Wasser told Superior Court Judge Stephen Moloney.
