One of the snaps shows the pair as tots adorably cuddled up together, while another features what seems to be a scrapbook page where Eilish has written "my friend zoe" under a picture of them dressed as elves.

The Ocean Eyes singer's natural blonde locks are on full display in the cute photos, though she's become better known for rocking black hair in recent years.

Eilish certainly has never been afraid to experiment with her style, as evident in her eclectic fashion posts.

Though she's back to rocking dark tresses, the Grammy winner did return to her natural hair color around the release of her sophomore album, Happier Than Ever in 2021.

Eilish has certainly found her stride when it comes to style, but she recently admitted the constant media attention surrounding her body continues to take a toll on her mental health.
