Who knew that celebrities had side jobs?!

Some of Hollywood's biggest actors, musicians and reality stars have huge companies or investments that most fans don't even know about! 

For example, the Kardashian leading ladies have books, games, clothing lines, clothing stores, hair products, makeup, nail polish, perfumes and more! Another popular celebrity mogul is Jessica Alba. After being frustrated with finding healthy products for her children, she launched The Honest Company, which offers safe, non-toxic and eco-friendly baby products.
