Having lived most of her life in Greenwich Village, Mia attends Albert Einstein High School with her few close friends (including her best friends, Lilly Moscovitz and Tina Hakim-Baba). Her special talent is writing and she chronicles the main aspects of her life in various personal diaries.

In the two Princess Diaries films, Mia Thermopolis is portrayed by Anne Hathaway.

Physical AppearanceEdit

At the beginning of the series, Mia is flat-chested, 5 feet 9 height, thin, and extremely large feet. During the events of Princess Mia, Mia grows an inch taller, developes a bust and becomes less of a "Q-tip".


Mia thinks that she is "not pretty, but not grossly disfigured". However, this can be argued as rather a lot of people think that Mia is very pretty. Her grandmother told her she was "really quite beautiful", and her distant cousin Sebastiano says the she "has a beautiful bone structure"


Mia is a sarcastic, funny person who lies a lot, making her nostrils flare. She is also very environmentally friendly,and loves animals,stating that she will never love anyone as much as her ginger cat, Fat Louie. Mia is worrisome, paranoid about Michael dumping her for either a smarter girl,a girl who is willing to "do it" with him or a "party girl". Also, Mia is quite romantic, writing love poems to Michael, who secretly loves her too, and insecure, constantly thinking of herself as a biological freak.

Mia's middle name is Mignonette and her username on Instant Messenger is FtLouie after her much loved cat.


Albert Einstein High School is headed by Principal Gupta. The school makes various attempts to celebrate and encourage diversity. For instance, the Cultural Diversity Dance in October, and the Non-Denominational Winter Dance. The school has a very complete core-curriculum, and prides itself in its gifted students. Mia is often sarcastic towards her placement in the Gifted & Talented class. She claims, she was put in the class to improve her lowly grade in Algebra. The teacher in charge of G & T is Mrs. Hill, who spends class time in the teacher's lounge across the hall. The mascot of Albert Einstein High is the Lion. Mia is now currently at Sarah Lawrence College and is done with high school.

As time passes, Clarisse teaches Mia about the life of being a princess and its duties and slowly they open up to each other. There are times when Clarisse questioned whether or not Mia could truly ascend the throne and be able to lead Genevoia to greatness, but learned through her granddaughter's actions that she is more than ready and capable. Although, they go through arguments and hardships, they have proven to be like best friends and truly love and care for each others well being. Clarisse admits to Mia that Mia reminds her of her.

Michael MoscovitzEdit

In Book 1 Mia doesn't realize that she has a crush on Michael, Lilly's older Brother, because she likes Josh Richter, who is one of the most popular guys in school. She and Michael share an excellent rapport and whenever the two start talking it's always a race to see who finishes first. Michael is described as the 3rd best looking guy in school after Josh Richter and Justin Baxendale. He has brown eyes, thick dark hair and is tall, handsome, and manly. In Book 1 he often flirts with Mia and says mean things about Josh so that Mia would change her opinion about him since he is aware of her feelings for him. He tries to ask her to the Cultural Diversity Dance but is interupted by Miss Hill. Mia runs away fearing that Michael might ask her to do math even on a weekend. Still, Michael shows up at the function to see whether Josh isn't doing anything wrong. After Mia publicly humiliates Josh, she spends most of her time talking to Michael. Michael finally asks her to dance with him and without hesitating Mia says yes. Everyone goes to Lilly's and Michael's house to watch Movies and return back except for Mia. Michael invites her to his room and plucks up the courage to play the song "The Tall Drink Of Water" which he writes for her but she doesn't get it.

In Book 2 Mia comes to know that she has a crush on Michael but is afraid to tell him. She starts getting messages from JoCrox, who is Kenny, her Biology partner.

After breaking up with Kenny she arrives at the dance only to be cornered on her way out by Michael, who has been called there by Lilly. The two of them talk and confess there feelings about each other and finally share a kiss.

In book 4 Mia is in Genovia and is ecstatic about getting together with Michael, but is worried that he loves her as a friend as opposed to being in love with her. Worried and confused,Mia calls Tina for help and gives Mia Michael's number. On the phone he seems really happy to hear from her, despite her missing his birthday, and is romantic with her. When Mia arrives back she finds a message from Michael telling her that he is worried about her as she hasn't called for a while and that she should call him back when she gets the message. However,Mia, at the urging of her grandmere, puts off calling him believing that Jane Eyre is right not to chase boys. However they exchange message on IM-ing. The next day Michael is just as happy to see her as she is too see him, and he asks her on their first date. However her happiness was short-lived as Grandmere has her ball on the same night as their date. However,despite her belief that Michael will break up with her due to her missing their first date, he understands and invites her over to his place. While there they kiss and have a nice meal, watch star wars and Mia gives Michael his birthday present which he loves. All of this leads Mia too believe that Jane Eyre's strategy of not chasing boys isn't necessarily the right thing to do about her relationship with Michael. It is implied that they made love in the tenth book, Forever Princess.
