She has also performed on Jimmy Kimmel and The Ellen Show - not bad for someone who hasn't even hit adolescence.
她也曾应邀参加《吉米秀》(Jimmy Kimmel)和《艾伦秀》(The Ellen Show)。对于一个青春期未到的人来说，有机会上这两个节目还算不错。

不像那些狂热追星的小女孩，玛蒂认为她一直都能保持着冷静的头脑，即使在格莱美颁奖典礼这种场合。因为她将自己视为一个明星，所以她需要表现得体。

在其他小孩想方设法逃课、不做作业的时候，玛蒂却对学业热情饱满，因为她不想自己成为又一个“愚蠢的舞者”。
As well as dancing, she has her eye on singing and acting - she has already acted in the TV shows Drop Dead Diva and Austin & Ally.
除了跳舞，玛蒂还唱歌和表演，她已经出演了电视剧《美女上错身》(Drop Dead Diva)和《奥斯汀与艾丽》(Austin & Ally)。

尽管小小年纪她的事业就取得了如此惊人的成就，但如果给自己的成就打分，且10分满分的话，玛蒂只给自己打9分。

她说：“1到10，我觉得自己只能拿9分，因为我一定还有提升的空间。我知道我可以走更远。”
