>> THE MODELIZER —Although rumors have placed Lily Donaldson in the hands of two other men in recent months, it looks like she's still with Carine Roitfeld's son Vladimir Restoin-Roitfeld.  The two arrived together at the Visionaire 55 party on Tuesday night.  And while we're talking model love, Anja Rubik does seem to be dating Sasha Knezevic, as the holiday Gap ads imply — they appeared together at the Gucci Tattoo Heart party just before Thanksgiving.
