The worst person you will ever meet. Major bitch and always gets her way. Lies to your friends to turn them against you and make them hate you for no reason. She always gets what she wants and only sticks with her same drama clique since elementary through the rest of her lies. The rest are just followers cause there too scared that she will make their life hell too if they're not her friends. Also Sierra's talk about everyone behind there back even friends. And she tends to date the same people as her best friends.
