Despite having just left San Carlos restaurant, the blonde beauty, who is famed for her role as Hannah Ashworth on the soap, looked as if she hadn�t eaten a thing.

After dining at the restaurant, the star headed to a party at Panacea with some friends and Everton footballers Victor Anachibi and Tim Howard.
Emma has always been slim but her recent appearance has sparked concern that she�s dropped a significant amount of weight.
Since leaving Hollyoaks in January, she has been trying to extend her acting repertoire and perhaps thinks that losing weight will help her career.
Despite allegedly thinking of moving to Los Angeles for Hollywood roles, she most recently starred in West End show Wolfboy.
Her three-week run in the play ended at the beginning of August and she received mainly positive reviews from critics.
Speaking of her role as nurse Cherry in the thriller musical, she said: �It�s a very different role.
�I play a nurse, and there are four people in the play in total. I�m loving it and it�s a new challenge and I can�t wait to get on to the stage.
�TV�s very different. I�m really enjoying theatre. When you�ve played something for five years it�s so refreshing to have a change and to work with different people.�
Last night she finished off her look with her trademark backcombed beehive.
