Rodrigo's friendship with Hu goes back to their Disney Channel days. From 2016 to 2019, the pair starred in "Bizaardvark" as best friends who post funny songs and content on the internet. While some friendships fizzle out after work wraps, Rodrigo and Hu's only grew stronger. In a 2021 Elle cover story, the "Good 4 U" singer called Hu "literally my soulmate."
That wasn't the only time Rodrigo has gushed about Hu. In a live stream, she also called Hu her "best friend in the whole world." Along with being a frequent person featured on Rodrigo's Instagram, Hu also starred in the singer's "Sour Prom" concert film in July 2021.
