I think Kathy is dull and as dumb as a box of rocks who got lucky with finding a rich guy (thanks to what their mother taught them about sexual stuff)... but I would be so annoyed if my sister's husband started his own competitive company after giving the guy his start.Kathy Hilton and Kyle had a huge blowout when Mo left Hilton to open The Agency. Kathy hated the idea of the show Kyle made loosely based on their mother (American Woman) and I can't imagine this show is doing much to repair the RHOBH rift.
And I like Mo, but that really took chutzpah.
