Last year, I was shopping for groceries and saw Cote de Pablo shopping with her husband and a small child. No makeup, and she looked like a woman in her twenties.
It's Los Angeles "etiquette" to not approach actors when they are with their families, doing family things. (They aren't on the job, and children can get freaked out by being approached by enthusiastic strangers.)
Anyway, I watched for a moment from several feet away, and she looked up and made eye contact with me. I smiled and gave her a thumbs-up, and she gave me a thumbs-up back.
It was a cute moment.
