Vienna Girardi continued her week of party-hopping and hob-nobbing as she attended OK! Magazine's 5th Anniversary Party on September 1 in L.A. Along with her constant companion, model and actress Amber Lancaster, Vienna posed for photos, mingled with other D-list celebs, and flaunted her brand new hairdo, before heading off for a late night at Hollywood's Budoir Lounge.
