Following a hilariously true introduction from host Chris Rock — “The one thing she didn’t lose at Weight Watchers was her voice” — R&B diva Jennifer Hudson took to the 2014 BET Awards stage to perform “Walk It Out” and to debut her new disco-soul-inspired jam “It’s Your World,” the latter of which features R. Kelly, however he wasn’t there to join her.
