Exclusive DetailsKim Kardashian did her best to keep the goings on inside her baby shower yesterday a secret, but she failed to wrangle her crazy Aunt Karen ... who blabbed all about the party to the paps ... but some of what she said was just plain wrong.
Karen Haughton, who is Kris Jenner's sister, clearly had a good time and was as chatty as can be as she made her way out. She struck up conversations with photogs and posed for pics with fans ... all while she spilled details of what went on inside.
Karen -- who may have had a mimosa or 2 -- had a couple of teeny-weeny facts wrong:
-- She said the guests scored Rolexes as shower gifts (not true)
-- Kanye and Kim are the same height (not true)
-- She says she ate cake, and then seconds later said there was no cake, just cookies
Aunt Karen, you're welcome at our baby shower any time.
