Trying to remember mainstream actress who had leaks of her masturbating with a dildo or vibrator

[NotInMyBackyard]

This would have been maybe ten years ago, give or take. I believe it happened before the big "fappening" leaks. In the photos (which weren't great quality), she is masturbating with a vibrator or dildo. She would've been in her early- to mid-20s at the time. Not a big name "A-list" actress. I think she was either American or British. For some reason the last name "Olsen" or "Olson" is jumping out at me, but this could be a false lead.

If I am right about the last name (and I could be wrong), I know it wasn't any of the following:
Ashley Olsen
Mary-Kate Olsen
Elizabeth Olsen
Kaitlin Olson
Bree Olson
