Khloe Kardashian is officially getting divorced from estranged husband Lamar Odom. The pair married four years ago after dating for only one month.

E! News reporter Ken Baker confirmed the report, tweeting on Friday, “Khloe K is filing for divorce today with Lamar. Tweet me your reactions …”

Rumors have been continuing for the past few months that Odom has been cheating and indulging in substance abuse. Two women have said they were Odom's mistresses and had sexual relationships with the 34-year-old NBA forward who played last season for the Los Angeles Clippers before becoming a free agent.  In November, he admitted to cheating on Kardashian, 29, in a bizarre rap video while drunk.  In August, he was arrested for allegedly driving under the influence. 

If the couple splits, Odom could potentially lose millions of dollars in the divorce settlement.

When the couple married in 2009, they signed a prenup, which reportedly says that Kardashian is owed about $500,000 for every year the pair was married; spousal support totaling $25,000 each month; $5,000 a month for shopping expenses; and $1,000 for beauty care. In addition, their $500,000 Rolls Royce, a $140,000 Porsche Panamera, and Kardashian’s $850,000 engagement ring would be divided among them.

Kardashian's net worth is estimated at about $18 million, while Odom has earned a reported $56 million during his 14-year NBA career.
