After topping a visitor survey to name Britain's best leading lady, the stunning figure of the Titanic star took centre stage in the A-List Party area of the London attraction, alongside the poll's second and third placed ladies, Mirren and Dench.
Kate's statute took four months to complete at a cost of £150,000, and is dressed in the Elie Saab dress she wore earlier this year to pick up an Emmy for her role in Mildred Pierce.
Other recent additions include Rihanna and Fergie from the Black Eyed Peas, while a figure of Patrick Swayze was recently unveiled by his wife, Lisa, at the Hollywood attraction.
