The 'Deliver Us From Evil' actress said she found the daily sessions with a personal trainer help ease the symptoms of the anxiety disorder, reported Contactmusic.
"To combat my OCD, a trainer helps me work out every day 6 am. I don't know what he does, but it helps. We talked over the weekend," she said.
The 33-year-old actress also admitted she never brushes her hair and isn't faithful to using any particular product on it.
"I'm Chinese so I have thick hair, which I don't brush, and use different products. I love vintage shopping."
