Kim Kardashian -- Donating $200k Instead of Returning Wedding Gifts

Kim Kardashian's wedding guests ain't gonna get their expensive wedding gifts back ... but KK wants to make it up to everyone ... with one BIG ASS charity donation.

Kim just blogged about her decision to divorce Kris Humphries ... insisting she "married for love" ... but says, "I got caught up with the hoopla and the filming of the TV show that when I probably should have ended my relationship, I didn’t know how to and didn’t want to disappoint a lot of people."

She also wrote, "There are also reports that I made millions of dollars off of the wedding. These reports are simply not true and it makes me so sad to have to even clarify this."

"I’m so grateful to everyone who took the time to come to my wedding and I’ll be donating the money for all the gifts to the Dream Foundation."

Sources close to Kim tell TMZ ... KK plans to give the organization a $200k check.
