Rumer Willis has control through twitter

Rumer Willis thinks twitter gives her "control" of her image.

The 22-year-old actress - who is the daughter of Hollywood stars Bruce Willis and Demi Moore - is thankful for "outlets" like the micro-blogging website because it gives celebrities like her the chance to defend themselves when they get talked about.

The '90210' star said: "Everyone has an opinion, and if they say something negative, you can't defend yourself because any response in itself is enough to validate the claim.

"But that's the great thing about outlets like twitter because, more and more, we're getting control of our image. We can be in direct contact with the world and people can at least choose between second-hand and the direct information."

However, Rumer admits being famous does mean she has to watch her image when she's out and about in public.

She explained to Prestige magazine: "You have to be a little more aware of how you present yourself in public places. I mean, I can't walk into Starbucks anymore in my pyjama pants."

Rumer also revealed being an actress was her ambition for a very young age, and was always supported to follow her dream by her famous parents - so long as she completed her education first.

She said: "I always wanted to do it from when I was super little, so it was more about just waiting for my parents to say it was OK. They were totally fine, they've always been completely supportive of it. They just wanted me to finish high school, which I totally appreciate now."
