United Kingdom, March 13 -- Kim Kardashian claims she paid for most of her engagement ring from Kris Humphries.

The 44-year-old reality star - who split from the former NBA player after just 72 days of marriage in October 2011 - has revealed how she "had to" give up the 18-carat emerald cut diamond ring in their divorce settlement two years later.

In the latest episode of 'The Kardashians', she said: "I didn't keep that. I was pregnant with North, still married to him, and in order to divorce him, he said I had to give him the ring."

However, she insisted she actually paid for the design, noting her ex "contributed a fifth" of the cost.

After the divorce settlement, Kris auctioned the jewellery off for a whopping $749,000.
