"I think I screamed when I found out," she said.
"I'm so excited, it's such an amazing opportunity to go overseas and show them what I've got, it's really great exposure for me. I honestly can't wait."
Stella said she was also delighted at the chance to travel overseas, something she hadn't done before.
She hoped she would have time during the two-and-a-half week trip to do some sightseeing in Hollywood.
"Coming from a small town, getting to go to LA, such a big, busy city, that's a huge privilege. I can't believe it."
Since primary school Stella has had a huge passion for singing, dancing and being on stage, she said.
Her ultimate dream is to become a professional singer, living overseas and sharing her music on a global scale.
"My dream is to share my music with the world.
"I love being able to make people happy through my music and seeing their reactions, it's a feeling like no other."
For the next few months Stella will be busy raising the $8500 she needs to get to Los Angeles. The trip to compete in the competition was not funded, she said.
Stella will be holding a fundraising concert at Okere Falls Store on April 24.
She encouraged people to come and support her and said people interested in contributing towards her trip could contact her on getstellatola@hotmail.com. For more information visit her Facebook page, facebook.com/StellaMarisMusic.
