We all thought that, Beyoncé's House of Dereon line would be a huge success! After all it is not everyday you get to debut your line on "The Oprah Winfrey Show" and certainly Beyoncé has the star power to carry her brand with the millions of dollars of media exposure she brings. That just goes to show no matter how big the star or brand, connecting with your target audience is the key. There must be a strategic plan and approach to reach your audience.

2. Jennifer Lopez - The biggest celebrity-owned luxury empire!

Encompassing a high-end collection, Sweetface; a juniors line, Justweet, and multiple fragrances. Together they are valued at more than $255 million. Lopez works in partnership with Tommy Hilfiger's brother Andy, and targets more mainstream tastes than Stefani. Mixing ladylike polish with sleek streetwear, the collection is intended as an accessible distillation of the elements that inform Lopez's diva persona. While Lopez doesn't play a design role like Stefani, her esthetic imprint is still visible in the clothing, including pieces like dramatic, draped jersey dresses and sexy romper suits.
