It's full steam ahead for Beyonce Knowles after the sexy singer claimed three nominations for the 2007 Soul Train Music Awards yesterday. The singer's IRREPLACEABLE hit, which has ruled the US charts for the past nine weeks, was nominated in the Best R+B/Soul Single and Best R+B/Soul or Rap Music Video categories, while her second solo album, B'DAY, is up for Best R+B/Soul Album, Female. Her three awards lead the Soul Train pack, but fellow diva Mary J Blige, Chris Brown, NE-YO, Gnarls Barkley, John Legend and YUNG JOC all picked up a brace of nominations apiece. The awards will be handed out at the Pasadena Civic Auditorium in California on 10 March (07).
