But now the reality TV stars are facing speculation their bubble might be about to burst.
A report in the New York Post today claimed the stars are 'no longer sought-after celebrities'.
The publication insists that there is a backlash brewing against the clan which is hitting them where it really hurts - in their very deep pockets.
The Post claims the family have suffered falling ratings, lost contracts and a decline in magazine pulling power following the swift demise of Kim Kardashian’s marriage Kris Humphries.
However, respected business and finance magazine Forbes has countered the report, insisting the family are still 'kashing in'.

This season of Kourtney and Kim Take New York is averaging its highest in four seasons with over 3 million total viewers each week - up 43 per cent from the prior season.
A spokesman told Mail Online: 'The most recent Sunday night premiere broke records as the most-watched episode of the series ever averaging over 3.3 million total viewers.
'These numbers are a very good indication of the staying power of this show, the continued interest in the family and the overall success of the franchise.'
The Post also reports that American tabloid magazine covers featuring the Kardashians have seen a drop in sales.

'To say that she was "dropped" or "replaced" is misleading and untrue. Skechers has enjoyed and continues to enjoy the relationship with Kim, and in fact we continue to discuss ways that we may work together in the future.'
But there has been a indisputable shift in attitude towards the family since Kim announced her marriage split.
Critics were fast to come forward to say she made a mockery out of marriage to make hard cash - a reported $18m.
There were calls to boycott the show from an online internet campaign - which garnered thousands of petitions - but the show went on, with E! bosses getting to rub their hands together at the extra 800,000 viewers an episode tuning in to watch Kim's marital meltdown
Meanwhile, it has also been claimed that both Kim and her sister Khloe have been keeping 90 per cent of the proceeds from their charity auctions on eBay.
According to Fox News' Pop Tarts column, the siblings both abide by the minimum amount they are required to give to charity through eBay's GivingWorks after auctioning off various personal items.
Glenn Selig, President/CEO of Selig Multimedia, told Pop Tarts: 'Many times the public assumes that all the proceeds go to charity and not the celebrity.
'But that is often not the case
