Sean Combs has added another business venture to his empire - the music mogul has signed a multi-year contract to promote vodka. The rapper has agreed to promote Ciroc vodka for a 50 per cent share of any profits. Combs, who also has clothing and perfume lines, will be responsible for marketing the brand. He says, "I'm not just a celebrity endorser, I'm a brand builder. I'm a luxury brand builder." The new deal could be worth more than $100 million (GBP50 million) for Combs, depending on how well the brand performs - and he means business: "It is not an endorsement deal. This is something that will have my daily attention."
