After almost four years of marriage and tons of speculation, it’s officially splittsville for Khloe Kardashian and Lamar Odom, according to the celebrity news site TMZ.

Rumors have been swirling around for months that Odom, a former basketball player and Kardashian, the youngest of the three famous sisters, have been having trouble in the land of matrimony–due to Odom’s alleged drug use. On Friday, Dec. 13, those rumors turned into reality in a Los Angeles County Superior Court, after Kardashian filed papers citing “irreconcilable differences” and requested to drop the ‘Odom’ from her last name.

As far as divorces go, this one should be pretty uncomplicated, as both Kardashian and Odom signed a prenuptial agreement that would allow both millionaires to keep their respective earnings, and since they have no children, they’ll obviously be able to avoid a bitter custody battle, which of course can turn a routine divorce into a long and nasty one.

Just think, everything seemed to be incredibly grand for the couple back in 2011 when their E! reality show “Khloe & Lamar” hit the airwaves. On the show, the couple appeared to be in matrimonial bliss and seemingly wanted to prove to the naysayers–including some of their family members–that their love was the real deal, despite knowing each other for only 30 days.

But back in August of this year reports of Odom abusing drugs started to surface, followed by some very bizarre behavior, including a public meltdown against the paparazzi and a disturbing video he recorded with his best friend Jamie Sangouthai. In the video, which shows the two freestyle-rapping with their shirts off, Odom talks about recreational drug use and cheating on Kardashian whenever she’s out of town and many have suspected the entire video performance was drug fueled. And just a few days ago, the 6′ 10″ former hoop star pleaded no contest in his ongoing DUI case.

According to a TMZ source, Lamar blames a lot of his bad behavior on his circle of friends but not himself.

My friends have been “supporting me the wrong way by bringing girls around,” he was quoted saying. And he feels Kardashian is to blame too. “She brings out the bad side of me.”

This marks the second big divorce story for the Kardashian clan, as big sister Kim went through the media rounds after leaving ex-husband Kris Humphries back in 2011.
