Kim Kardashian’s marriage to Kris Humphries may have been short-lived, but the reality star is making sure her wedding guests know that their gifts were not sent in vain.

The 31-year-old sent a letter to everyone who attended her big day, informing them that she had calculated the amount the presents were worth and then made a donation to a good cause.

Sources close to the NBA star tell us … Kris is adamant that gifts from a fraudulent wedding should be returned.

Kris gives Kim props for cutting a check for twice the value of the gifts and giving it to charity … but he feels Kim should have made the contribution IN ADDITION to returning the gifts know Kim made 17.9 million form their nuptials. Which is reasonable.

Kris has told friends he feels the guests were duped into spending their hard-earned cash on wedding gifts … claiming Kim never intended to give their marriage a real chance.
