Rochelle chose to wear a daring white gown - featuring a v-neck and split to the waist - to the event, held at London's Royal Festival Hall, and looked smouldering on the red carpet,
The pop star and TV personality's frock did, however, have a striped nude panel which covered her modesty. Phew!
Rochelle teamed her floor-length dress with a chunky choker and she wore her hair in a sleek undo. The mum-of-one, who is married to former JLS star Marvin, completed her look with sky-high sandals and bronzed make-up.
Tonight's glitzy event kicks off at 8pm and will be aired on BBC One. Other stars who have also been spotted on the red carpet include Ferne McCann and Michelle Keegan and husband Mark Wright.
