All info was provided Amy Sanders at Lizzie McGuire Wiki
Amy Sanders is Kate's eighteen-year-old cousin. She is in a band and is not very responsible. She is practically like an older version of Kate, but only far more self centered and immature.
Kate and Amy seem to have a rocky relationship, as shown in the episode "Party Over Here".
She invited only her own friends who proceeded to deliberately break stuff. She also ignored Kate's request for a chocolate birthday cake because she liked strawberry, and she didn't even know that it was Kate's birthday. When she does find out, she only wishes Kate a happy birthday before returning to the party.
Kate is also shown to be a lot nicer and mature than Amy, despite Amy being older than Kate.
Amy also appeared in "Clue-Less" and "Xtreme Xmas".
