Actress Emma Stone has revealed that she has been in therapy since she was seven years old to treat her anxiety.

The Oscar-winning actress appeared on The Late Show with Stephen Colbert where she opened up about her battle with anxiety and how therapy and acting have helped her cope through the years.

The La La Land star brought along a drawing she made in therapy when she was nine, saying: "This is me, I guess, and this is anxiety, a little green monster that looks a little bit like, as someone backstage said, a uterus with some ovaries. I didn't mean it to be hormonally related in any way, as I said, I was nine.

"I was a very, very, very anxious child and I had a lot of panic attacks. I benefited in a big way from therapy, I started it at seven."
