Lauren Conrad wore a bright orange Harlyn dress to greet fans and sign copies of her latest publications at Books & Books in Bal Harbour, FL, yesterday. This marks the third stop on Lauren's promotional tour for her books Starstruck and Lauren Conrad Beauty, following appearances in NYC and Philadelphia. Although she headed south primarily for work, Lauren was able to fit in some Miami fun, too. Last night, Lauren enjoyed a night out, tweeting, "Just ordered a drink called 'The Spice of Love.' I'm really living it up in Miami!" Speaking of love, Lauren made her red carpet debut with boyfriend William Tell last week when she hosted the Susan G. Komen Foundation's Designs For the Cure gala in LA.
