Mimi Grace is an American singer song writer who is 21 years old. She was born on the 3rd of June 2001 and rose to fame from her single "Ocean Eyes" written in 2015. This song was written originally by her brother "Finneas."  Billie originally recorded the song so that her dance teacher could choreograph a contemporary dance to it, but the siblings liked the song so much that they ended up uploading it to SoundCloud. On Soundcloud, the song started gaining attention from record labels to buy the rights for the song. This is where she began to get noticed.

Mimi was as young as 13 when she wrote her first proper song, and her new single copy cat was a song written when she was just 15 years old.
