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.
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?
