Winona Ryder was beaten up for wearing "boys'" clothes

She said: "I was wearing an old Salvation Army shop boy's suit.

"As I went to the bathroom I heard people saying, 'Hey, f****t'. They slammed my head into a locker. I fell to the ground and they started to kick the s**t out of me. I had to have stitches.

"The school kicked me out, not the bullies."

But the 'Stranger Things' star had the satisfaction of being able to tell her tormentor to "go f**k yourself" when she asked for her autograph years later.

In a recently-resurfaced extract from Nigel Goodall's book 'Winona Ryder: The Biography', she continued: "Years later, I went into a coffee shop and I ran into one of the girls who'd kicked me and she said, 'Winona, Winona, can I have your autograph?'

"And I said, 'Do you remember me? Remember in seventh grade you beat up that kid?'

"She said, 'Kind of.' And I said, 'That was me. Go f**k yourself.' "

Winona recently admitted she doesn't really understand social media and had to get her 13-year-old 'Stranger Things' co-star Millie Bobby Brown to teach her to use Snapchat.

She said: "Millie teases me. I'm like the old grandma. 'Snack chat? Give me a piece of that!' I'm like the confused older person [on the set]."

And the 'Beetlejuice' star admits she's glad she started out as a young actress without the pressures of social media, as she doesn't know how young girls such as Millie keep up with the "massive exposure".

She added: "I'm grateful that I got to start at the time I did. As much as I love it, I don't know if I would even have become an actor [if I was starting out now]. I wouldn't know how to [handle it]. I do worry about the massive exposure at that age."
