The 30-year-old actress - who has recently been romantically linked with `Glee` star Matthew Morrison - insists she is able to keep her private life under the radar because she would rather go on dates to unpopular places, rather than frequent establishments known to be visited by celebrities.
She said: "Over the last year, I`ve dated guys that, if people knew, would be on the cover of magazines. But they don`t find out because I say, `Hey, would you like to go to Valencia?`
"Some people go to restaurants that are so popular. They say it`s really good food. You`re like, `What food is worth that?` The lobster ceviche will be just as good in a to-go box."
Olivia insists she will always be open and honest with people when they ask her questions, but she admits the reason she does so is in order to maintain her privacy in other areas.
She explained to Audrey magazine: "I feel like I`ve been given a lot and I try to say thank you. The only thing I ask of myself is to try to keep my personal life personal.
"I will take as many pictures as you want, I will try to answer every single question under the sun, and the reason I`m doing that is so you`ll realise that I just have to keep something for myself."
