Health beverage producer The Purple Beverage Company has signed up Grammy-winning singer Chaka Khan as its new champion.

The tie-up with Chaka Khan will coincide with her Broadway debut in the musical The Color Purple, scheduled to open in January.

The company said Chaka Khan will serve as a spokeswoman for, and work directly with, The Purple Beverage Company "to develop musical events that benefit The Chaka Khan Foundation and The Purple Beverage Company's various charity initiatives".

"We are excited to work with Chaka Khan. She's a true legend," said Purple Beverage CEO Ted Farnsworth. "Chaka's is a beautiful star that continues to shine as brightly as ever. We are thrilled that she has chosen to shine a bit of that light on Purple."

The Purple Beverage Company produces an antioxidant health beverage under the brand name Purple, which is currently available through health food stores, restaurants, delis, drug stores, supermarkets and convenience stores in selected cities, including New York, Los Angeles and Miami.

Purple Beverage said it expects retail distribution to be extended nationwide during this winter.
