Hilary Duff Blogs After Haylie’s Birthday Bash

Hilary Duff checked in with fans on her blog over at AOL’s KOL service on Thursday (March 2). “We celebrated my big sister Haylie’s 21st birthday by throwing her a huge birthday bash,” Hilary wrote. “The party was held at a very cool LA club. She wore a beautiful dress. We invited 400 people and over a thousand showed up! It was so exciting and so much fun. She was so happy after seeing the amount of people who came out to celebrate her day. My mom, dad, producers, directors and actors came. Mattel sent Haylie a huge Barbie doll birthday cake and we had a special toast. After that we danced the night away. It was good to see Haylie have fun and enjoy herself. I can’t believe she’s 21.”
