“Ruin The Friendship” is about stepping out of a platonic relationship and crossing the boundaries with said person. Prior to the album release, Demi revealed to MTV that there was a song they were nervous to release because they knew it would make headlines.

In an interview for Noisey, they stated that the song isn’t related to Wilmer Valderrama, who they used to be in a long-term relationship with. Fans believe they’re singing about one of their oldest friends, Nick Jonas, based on the lyrics.
