Meg Cabot, known for her books, The Princess Diaries and many others, has a blog/diary and it is really really PINK.
It is also very very funny.
UPDATE: Her latest entry about her dinner at Outback Steakhouse is hilarious. She also mentions that she will be chatting with fans at the Meg Cabot Book Club, Thursday, April 28, 2005 at 7:00pm about Princess Diaries 6. She is hinting about a spoiler for Princess Diary 7.
Looking aroung the Book Club site I have found very cool desktop wall paper, screensavers and buddy icons in the Freebies section.
