When today's hottest rapper is lost for words on hearing a new soulstress, she must be a future superstar. But it's an even bigger deal if that divette is Australian. Flo Rida was stunned by Jessica Mauboy's crunk 'n' B hit Running Back. "He couldn't believe it," Mauboy relates with a bashful laugh. "He was just like, 'What! She's an Australian artist? Where is she? What is she doing? Is she bringing out an album?' He was basically asking all the questions. He was really keen to know."
