RIHANNA insists shell be forever grateful for her smash hit song Umbrella. The singer says the chart-topping record which also features lyrics from rapper Jay-Z helped boost her music career, as well as landing her a huge endorsement deal. I did have a deal with an umbrella company and they had a range of very good umbrellas, Rihanna said. This is kind of weird because I grew up in Barbados and theres not a great culture of umbrellas like there is in the UK and Europe. SS
