Bloggers have become a huge part of Internet culture and many would say that Perez Hilton can be largely credited for that. The 33-year-old celebrity blogger (whose real name is Mario Armando Lavandeira, Jr.) has been blogging about celebrity gossip since 2005.

Now that Perez Hilton has gained a huge amount of followers, the blogger has decided to branch out into the world of designing clothing and most recently, writing a children's book.

Hilton is a huge advocate for "It Gets Better," an anti-bullying campaign and frequently speaks out about the unfortunate consequences of homophobia, teen bullying, and suicide.
