(PRNewsFoto/Destination Maternity Corporation) Being rich doesn't always accompany being famous, especially when living a rock star lifestyle, but a handful of A-list musicians have managed to turn their celebrity into successful business ventures: Jessica Simpson: You wouldn't expect a pop singer/reality star who didn't know the difference between chicken and tuna to morph into a fashion mogul, but that's the case of Jessica Simpson. She recently sold a 50% stake in her empire of clothing, shoes, and bags that's said to be worth more than $1 billion. Jay Z: The music mogul once rapped: "I’m not a businessman / I’m a business, man!" The rapper now can count clothing, sports bars, liquor, fragrances, a basketball team, and a music streaming service among his many ventures. Gwen Stefani: The No Doubt vocalist once sang of being "just a girl," but in addition to her solo career and gig on The Voice, she has managed to create a fashion company reportedly worth more than $90 million. Justin Timberlake: The former boy band singer has his hand in many businesses including a clothing line, record label, restaurant, basketball team, and most recently, his own brand of tequila. Gene Simmons: The KISS singer and bassist is reportedly worth more than $300 million, thanks to his role as the band's finance manager and his idea to license tons of merchandise. "Life is business, and I approach life the way sharks approach life—they must keep moving or else they will drown," he recently said in an interview.
