Leo's main squeeze, Bar Rafaeli, made an appearance at the Donna Primavera Summer 2008: Just Cavalli event (where we saw Tara Reid as well). Bar is certainly a stunner...but what about that little dog? He's stealing the spotlight! How cute is he?!? Since so many celebrities seem to carry their pooches around like accessories, I guess it's now become acceptable to bring them to fashion events too!Click on thumbnails to enlarge.
