Tonight is Kelly Killoren Bensimon's Birthday party at the newly opened "The Gates" lounge in Chelsea.  The real housewife will be celebrating her 41st birthday with her "closest" friends.  (RSVP address has been removed). Will Kelly show up on time to her own party?  We wouldn't bet our first born on it, but this should be fun regardless, mainly because we are looking forward to scoping out the new space.  And Kelly, who is really selective remember about putting her names on things...will also be hosting a Mother's Day celebration shopping event at the Juicy Couture Flagship store on Tuesday.
