Eva Mendes who has welcomed daughter Esmerelda Amada on September 12 with boyfriend Ryan Gosling has looked fit when she came out comfy and casual in a black cardigan, trousers and brown platform booties. The ‘Ides of March’ star had stepped out in Los Angeles on Halloween and no one could ever guess she’d given birth just around seven weeks ago, E!Online reported. The 40 year old said that she would give credit to her genes. The insider has revealed that the model cum actress has been drinking more water and tea than ever, as well as following a high protein/low carb meal delivery plan and eating traditional Spanish dishes her mother cooked for her. The Spanish beauty is being careful to take in an extra 300 calories a day the same amount she added to her diet while pregnant. Mendes has been taking it slowly as a new mom and not following a strict exercise routine yet.
