Simu Liu, a Marvel star who will soon be a Ken doll, has a new song called “Don’t.” Liu said on social media that he got the idea for the heart-wrenching ballad from the hard times in his own life.

Liu wrote on Instagram, “This song was written for all of the hard times in my life where I have questioned my worth and felt like an imposter.”

“It is for every single person who ever has felt alone, different, heartbroken or hopeless. You are worthy. You belong. You matter. I had the experience of a lifetime working on this record with @88rising. Our journey together is just beginning. More to come soon!”

Liu’s most well-known works are the superhero film Shang-Chi and the fantasy epic The Legend of the Ten Rings. The actor recently released a virtual duet with Riley Keough and sang a live rendition of an Avril Lavigne song at the Juno Awards for the singer herself.

As part of Shang-Chi: The Album, the actor also put out the single “Hot Soup.”

One True Loves, which is based on a book by Taylor Jenkins Reid, is the actor’s newest movie. It comes out in theaters on April 7, 2023. Ryan Gosling and Liu both appear in Barbie as one of the many Ken dolls.
