Hannah Hart

You can't think of Hannah Hart (aka Harto) without thinking of her YouTube series "My Drunk Kitchen." The California native, who was born on Nov. 2, 1986, went viral in 2011 when she decided to get wasted in her sister's kitchen, make a grilled cheese sandwich without any cheese and record the whole thing. The video still remains the YouTube star's most popular clip to date with almost 4 million views. Hannah, who graduated from UC Berkeley in 2009 with degrees in English literature and Japanese language, has accomplished a lot since then: In 2013, she won the Streamy Award for Best Female Performance in a Comedy. In 2014, she co-hosted the Streamy Awards with her BFF and fellow YouTuber Grace Helbig and also took home the Best Comedy award for her "My Drunk Kitchen" series. She made her movie debut in the 2014 indie comedy "Camp Takota" alongside Grace and social media star Mamrie Hart. That same year, she released her first book, "My Drunk Kitchen: A Guide to Eating, Drinking, and Going with Your Gut," which made The New York Times bestsellers list. She also recently signed on to work with food app Dysh with her YouTube BFFs Grace and Mamrie as well as her ex-girlfriend, digital star Ingrid Nilsen. Hannah, who has 2.5 million subscribers on her channel and counting, also started Have a Hart Day, an initiative to get fans across the world to help out and pay it forward.
