Hilary Duff: Puppy Love at 'Elixir' Book Signing!

Hilary Duff greets fans and signs copies of her new book, Elixir, at Books & Books on Friday (October 15) in Bal Harbour, Fla.

The 23-year-old singer and actress jetted in from New York where she also had been promoting the book.

“Thx too [sic] all that came too [sic] signing in miami! soo sweet to me! means so much!” Hil wrote on her Twitter page.

When one fan brought a dog to the bookstore, The Duffster started feeling a bit homesick!

“I also got some puppy luv. someone brought their pug! Makes me miss my babies bad! three more days!” she tweeted.

FYI: Hil is wearing J Brand “901″ leggings in Brigade.
