Trish De la Rosa

"Guess who got a job at...?"

- Trish's catchphrase

Patricia Maria "Trish" De la Rosa is a 17-year-old girl, a fashionista who becomes Austin Moon's manager and friend. She has also been Ally's best friend since kindergarten. She's known to wear a lot of crazy uniforms, because she goes through lots of jobs and gets fired very fast. She tends to get annoyed with Dez often; they are currently frenemies. Trish is the type of person who loves having a loud outfit. She can be a bit bossy and lazy, but always means well and looks out for those close to her. She is a part of Team Austin and manages him and his career well. Trish can be a really selfish person, but other than that she's a great friend. Her jobs are known to frequently change or she would get fired due to lack of discipline at work; however she takes her job as being Austin's manager very seriously.

She is portrayed by Raini Rodriguez.

Personality
Trish is portrayed as loud, lazy, obnoxious, fiery and a bit selfish. She's extremely loyal to her friends and shows deep compassion for them in their time of need. Trish is always there to keep them on the right track and not let their delusions get the better of them, whether it be Austin's immaturity, Ally's dreamful nature or Dez's eccentricities.

She's shown to dislike labor of any kind and is often seen to only take initiative in things she truly cares for, as in fashion, managing tactics and her friends or family. She's also a bit self-centered and loves the spotlight when it's on her, though for the most part she's perfectly fine in the sidelines. Her temper is also shown to be fiery and everyone knows that.

Trish is shown to be a short, plump teenage girl with long, curly raven hair, dark brown eyes and light olive skin.

Her fashion style is bold and daring, with her trademark animal print fabrics and bright colors. She usually wears colorful skinny jeans with a flowing blouse, often paired with a blazer or jacket and flats for shoes; very rarely does she ever wear heels.

A signature accessory she's grown to have is head pieces that she seems to attain with every job she goes through.
