Hot Shots: Who's That Hillzie Wearin' Thigh-Highs??

Lately, Lo's been spending a lotta time getting reacquainted with her old pal Kristin. But that doesn't mean she's forgotten all about her ex-roomie, Audrina. Yesterday, the Hillzies met up at an outdoor cafe in L.A. to grab some grub and (we assume!) to chit-chat about 'Drina's recent run-in with a certain ex-boyfriend.

Check out these shots of the girls catching up at Fratelli's, plus peep these pix of Audrina showin' some serious skin at last week's Los Premios awards.
