Kim & Kanye -- BOOED By Hecklers At Paris Fashion Show (VIDEO)

Kim Kardashian and Kanye West got another bad reception in Paris ... arriving late to a fashion show where a couple of hecklers booed them.

Kim -- who FYI wore nothing underneath her blazer -- and Kanye showed up at the Lanvin fashion show after it started ... and as they walked to the front-row, several dudes staring booing them.

Kanye gets defensive -- dropping the name of Alber, the designer throwing the shindig -- saying he wanted to see them ... implying they were only late because they were backstage talking to the designer.

Did we mention Kim's boobs?
