Revealed: Khloe Kardashian 'will get a total of $7m in Lamar Odom divorce'... which includes that 12.5 carat diamond sparkler

Marriage pays. That is if you're Khloé Kardashian.

The December 30 issue of UsWeekly revealed the reality star will gain a fortune when she divorces her husband of four years Lamar Odom.

In addition to keeping their $4m Tarzana mansion and her $1m diamond engagement ring, the 29-year-old will be awarded a $2m cash payout.'Khloé and Lamar have nothing to worry about as far as fiances,' a source tells UsWeekly. 'Their prenup is ironclad.'

And the prenup sways in favor of the Instagram addict who is set to get a chunk of the NBA star's reported $116m earnings.

The magazine revealed, 'For every year of their four-year union, she will receive $500,000.'That means the daughter of Kris Jenner - who filed for divorced on December 13 - is lined up to get a $2m cash payout after her lawyer Laura Wasser (who also represented sister Kim Kardashian when she parted ways with husband Kris Humphries) ties up all the details.

It's also stipulated in their prenup that the cover girl get to keep all 'gifts.'

That will include all those fancy wedding presents as well as her wedding rings.

That's right, the Vartan 12.5 carat radiant-cut diamond ring - which the beauty slipped off on November 23 after seeing Lamar confess to cheating during an impromptu early November rap video - will remain hers.What will Khloé lose after the divorce?

The $10m life insurance policy on the former Lakers basketball player.

'Khloe will remain the beneficiary until they get divorced,' said Us. 'Or until they both agree in writing to change the policy.'

The Kardashian Kollection designer - who is reportedly seeing Dodger Matt Kemp - will also drop the name Odom.

As far as spousal support, Khloé is not asking for any, nor does she want her spouse to ask for any.

As far profits from their unisex Unbreakable fragrances and royalties from Khloé & Lamar, it's not yet been reported how those will be divided.
