Previously, Jauregui was notably romantically linked to rapper Ty Dolla $ign from 2017 through 2019. Last year, she released a single called "Always Love" about the breakup and spoke to PEOPLE about its inspiration.

Written shortly after they split, she crafted the ballad during trips to Bali and London alongside collaborators Trey Campbell and Malay while experiencing a flurry of "raw" emotions. "I was feeling the feelings of complexity that are getting out of a relationship that you still want to be in and wish could work, but just wasn't working for you anymore," said Jauregui at the time. "I, still to this day, have a lot of love and respect for him and what we had together."
