Hilary Duff has finally become the member of Twitter. The 23-year-old beauty, who just wed ice hockey star Mike Comrie on August 14, officially joined the micro-blogging site on Sunday, October 10.

Hilary promoted her new young-adult novel, which she wrote with Elise Allen, at Borders Books & Music, Columbus Circle in New York City. Of penning a book, she said in a past interview, "I wrote a book, so it goes to show you that anyone can write a book if they have an idea."
