The 31-year-old actress recognised her journey in an Instagram post early this week, reported Us magazine.
"This year was one of a kind, she began. And a kind one to me. There was lots to be done. And a whole lot to see. I had family and friends, and colleagues galore, now I have fans, plus a million and four!
"You tweet and you post. And you instagram too. You chat, comment, draw. You just do what you do. And though I don't answer 'Cause time is a-tickin', Know that you matter. By the posts that I'm pickin'. I keep posting 'Cause I know that you care, And I care to post. When I know that you're there," she writes.
