R+B singer Rihanna is confident who will be the big winner at this year's (07) MOBO Awards - her idol Amy Winehouse. The Umbrella hitmaker, who received a nod for Best International Act, wasn't surprised Winehouse dominated this week's (22Aug07) nominations in four categories, including Best U.K. Female and Best R+B Act. She says, "She's an amazing artist. She's one of my favourite artists in the U.K. and I'm glad she's nominated because she deserves it." The 12th annual Mobo Awards take place at London's 02 Arena on 12 September (07) and will be co-hosted by singer Jamelia and reggae artist Shaggy.
