Beyonce denies disrupting rival's launch

Beyonce Knowles has slammed claims the launch of her new album was timed to interfere with former Destiny's Child bandmate Letoya Luckett's debut.

Luckett, who left the band in 2000, released her first album last week, the same date Knowles made her forthcoming record B'Day available for pre-orders, ahead of its September 4 release date.
