Kathy Hilton says her daughter pushing back her wedding date is no cause for alarm ... and guess what -- when it goes down it ain't happening at a Hilton.
We got Paris' mom at LAX Wednesday afternoon ... she tells us Paris has been swamped promoting her new fragrance and skincare line, so she's got no time at all right now to tie the knot with Chris Zylka.
Kathy assures us she was with the couple recently and all's well -- no cold feet or prenup issues. Then again ... we're still not entirely sure Kathy knows what a prenuptial agreement is all about.
According to Kathy, whoever makes the final cut is just going to have to wait for the official invite ... when Paris gets more free time.
