The 37-year-old actress - who has been in a relationship with George Augusto for nine years - is hopeless in the kitchen so relies on restaurant food and home deliveries to ensure she gets the nourishment she needs.
She admitted: "I open the fridge and don`t know how to get from point A to point B. I do want to start because I feel really pathetic - at a certain age you`ve got to learn how to provide for yourself.
"We get home delivery meals three times a week and we go out the rest of the time. It`s so embarrassing."
Despite her lack of culinary prowess, Eva loves hosting her friends at her home for "girls` day" - and manages not to get involved in any of the catering.
She said: "I quite often have a girls` day on a Sunday where they all just come over and we talk about anything and everything.
"We get graphic, we get medical, we get emotional. There are no boys allowed and no alcohol, just tea and juices and one of my friends gets cupcakes.
"Some of the girls cook but I don`t - I just set the ambience. My thing is flower arranging."
