The Countdown legend, who was hosting the annual event, looked incredible as she posed on the red carpet outside London’s Grosvenor House.
Wearing her blonde tresses down in soft waves, the 56-year-old channelled a sexy Jessica Rabbit vibe in a slinky red look.
Carol’s incredible assets were impossible to miss in the figure-hugging gown, which came complete with a front split.
The presenter happily showed off plenty of cleavage thanks to the lace neckline’s low-cut design, which featured sheer panels on the tum.
