The Destiny's Child star is in LA, ahead of the new series of X Factor USA, and looked sensational when she stepped out for dinner this week.
After a stint on the UK show, Kelly is now a judge on the American version, joining Simon Cowell, Demi Lovato and Paulina Rubio.
We love Kelly's relaxed version of the LBD, shunning a glam get-up for a chic shirt style take on the trend.
Kelly still managed to flash a bit of leg with a daring side split.
The singer continued the black theme with the rest of her outfit, sporting a vintage-style black Chanel handbag and chunky black loafers. She kept her make-up natural and swept her hair back with a retro black hair bow.
Top marks, Kelly!
