Qream, a vodka-based cream liqueur, will be aimed at “contemporary women who work hard and want to relax with friends at the end of the day,” says Williams in a statement.
The producer/singer was “instrumental”, Diageo claims, in developing the drink’s design and marketing strategy.

Qream will be launched in the US in July with events across the US. There are currently no plans to launch the brand in the UK.
