Who even is Grimes? The Canadian musician's real name is Claire Elise Boucher. Grimes is 30 years old and known for her synth-pop and electronica type of music. She was originally born in Vancouver, Canada.

She's not only a musician, she's also a songwriter, record producer and visual artist. She definitely has a unique style. Her Instagram is filled with psychedelic photos.

It looks like Musk has moved on from Amber Heard and he's happy in his new relationship with Grimes.
