“My parents are here,” Rashida Jones deflected, as an attendee pressed her for more details about an intimate scene gone awkward in a suite at the Chateau Marmont.

Indeed they were, as Quincy not only had two security guards shading his table at the intimate Russian Standard after-party, but also provided the VIP “lap....
