Olivia Munn finds daily 6am sessions with a personal trainer helps her keep obsessive compulsive disorder (OCD) at bay.
Munn finds the daily sessions with a personal trainer help ease the symptoms of the anxiety disorder - which sees sufferers experience obsessive thoughts and often indulge in repetitive behaviours - though she is unsure how they keep her calm.
She said: "To combat my OCD, a trainer helps me work out every day 6 a.m. I don't know what he does, but it helps. We talked over the weekend."
The 33-year-old actress also admitted she never brushes her hair and isn't faithful to using any particular product on it.
She said: "I'm Chinese so I have thick hair, which I don't brush, and use different products. I love vintage shopping."
And despite her slender frame, Olivia insists she never diets and is always happy to indulge in her favourite foods.
She said: "I don't diet. I eat plenty. Lunch was chicken marsala, miso soup, spare ribs. I send up Korean and Indian room service."
The actress will next be seen in supernatural thriller 'Deliver Us From Evil', which is based on a true story and she found it helpful having the person her character is based on on set with her.
She told the New York Post newspaper's Page Six column: "The film's based on a true New York story. I play the real cop's supportive wife. They're now divorced. But she was on set with me and led me through how it all was."
