In a note on her Facebook page, Jada Pinkett Smith is sticking up for Justin Bieber and Quvenzhane Wallis, and any other young star in the media today.

She writes: "How can we ask for our young stars to have a high level of responsibility if we are not demonstrating that same level of responsibility towards them?"

The actress, 41, goes on to say that in the last week she has been "trying to differentiate cyber-bullying from how we attack and ridicule our young stars through media and social networks. It is as if we have forgotten what it means to be young or even how to behave like good ol' grown folk."

Does being famous absolve the media of responsibility? she asks.

"Is it okay to continually attack and criticize a famous 19 year old who is simply trying to build a life, exercise his talents while figuring out what manhood and fame is all about as he carries the weight of supporting his family as well as providing the paychecks to others who depend on him to work so they can feed their families as well?"
