Justine Ezarik (pronunciation: /iːˈzɛrɪk/; born March 20, 1984), is an American viral video comedian, and Internet personality. She was originally based in Pittsburgh, Pennsylvania, but now works from Los Angeles. She is best known as iJustine, a lifecaster who communicates directly with her thousands of viewers on her Justin.tv channel, ijustine.tv. She has made more than 400 videos, including videos on such subjects as Lost and parkour. Her videos have received more than 25 million views - with 16 million on YouTube alone. Her popularity is such that a video about her wanting to order a cheeseburger got 600,000 YouTube views in a week. She is sometimes described as a "lifecasting star," a "new media star," or one of the web's most popular lifecasters. In 2008, she relocated her base of operation from Pittsburgh, Pennsylvania to Los Angeles, California.
Ezarik is known for her "300-page iPhone bill", which followed the first month of service after the introduction of the iPhone in 2007. The viral video earned her international attention and celebrity. The bad publicity that AT&T earned as a result of her video featuring her reviewing this bill and similar stories coincided with the announcement that detailed billing would become optional for iPhone users. As of June 1, 2009, she had over a half a million Twitter followers, and almost 100,000 subscribers to the iJustine YouTube channel. By December 2009 these numbers had grown to about 1 million Twitter followers and 300,000 YouTube subscribers, and USA Today estimated that her videos have attracted a total of 64 million viewers. She has also guest-starred on the YouTube show "The Annoying Orange" as Orange's love interest Passion Fruit. Her television acting credits include guest appearances on Law & Order: Special Victims Unit, Criminal Minds and The Bold & The Beautiful.
