Justine Ezarik might not be a household name, but the 25-year-old has a cable TV-size audience. The only difference: Ezarik’s audience is on YouTube, Facebook and Twitter.

Thanks to Google, she’s also now part of Carl’s Jr.’s effort rolling out this week to sell the Portobello Mushroom Six-Dollar Burger to young men. The search-engine giant drafted Ezarik and eight other popular YouTube creators to participate in an ad campaign for the fast-food chain on the video-sharing site. They were commissioned to put their own spin on the CKE Restaurants brand’s infamous Paris Hilton-eating-a-burger commercial by showing how they would ear theirs.
