Rumer Willis left feeling "awful" by online bullies

She admitted: "It was really hard. I would read that stuff and feel awful. I thought, 'I don't even get a chance?'

"People still don't necessarily know that I work - they just have opinions."

The 'House Bunny' star admits she was sometimes "ill-prepared" for life in the spotlight but still took the online abuse "really personally".

She told People magazine: "I would go to an event and I didn't realise I needed to do my make-up,.

"Online, people really started getting ugly .... People always say, 'You signed up for this, you're an actor,' but I used to take it really personally."

But these days, Rumer - who is competing on the current season of 'Dancing With the Stars' - has learned not to worry too much about what other people think of her.

She added: "If you let your value be determined by what other people think, you're screwed."
