This Sag star may be the most powerful celebrity...Lucky Jupiter rules Sagittarius, meaning many of them rise to great heights in their careers.
Rapper Jay-Z rose out of the Bed-Stuy projects to become one of the most powerful music figures, not to mention half of a power couple with Beyonce Knowles. He's earned enough to start his own label and foster other talents as well. But Jay-Z also has his eye set on giving back, in true Sagittarian fashion.
He's met with United Nations Secretary General Kofi Anan to discuss the global water shortage and has worked with Sean "Puff Daddy" (or P. Diddy depending on the day) Combs to support the Red Cross and other natural disaster relief efforts.
