Camila Cabello appears to allude to her recent reunion with Shawn Mendes at Coachella in a sneak peek of a new song. The 26-year-old "Havana" singer posted a brief preview of the track, saved on her phone as "June Gloom," on Instagram.

In the snippet, Cabello sings, "How come you're just so much better? / Is this gonna end ever? / I guess I'll f--- around and find out / Are you coming to Coachella? / If you don't, it's whatever / If you do, honey, it'll be all I think about." She captioned the post with "4.12 ."

Cabello's representative did not immediately respond to PEOPLE's request for comment.

Last week, images and videos of Cabello and Mendes, 24, together and kissing at the Indio, California music festival circulated online. A video posted on 102.7 KIIS FM's Twitter account showed the two engaged in conversation while holding drinks. Another clip, shared by a Mendes fan account, captured the couple enjoying a performance and sharing a kiss.

Following their Coachella sighting, a source informed PEOPLE that the singers had reconnected several months after announcing their breakup in November 2021. "They have been friendly for several months and hung out," the insider shared. "They always seemed to have a special connection."

Cabello and Mendes' relationship began in July 2019, with numerous PDA-filled moments captured before their first major public appearance at the MTV Video Music Awards in August that year, where they performed their duet "Señorita." The couple spent the early months of the COVID-19 pandemic quarantining together in Miami with Cabello's family, prior to announcing their split.

At the time, both shared the same statement on their Instagram Stories, which read, "Hey guys, we've decided to end our romantic relationship but our love for one another as humans is stronger than ever . We started our relationship as best friends and will continue to be best friends." The statement concluded with thanks for fans' support: "We so appreciate your support from the beginning and moving forward, Camila and Shawn."

Cabello's song teaser is the first new music she has shared since the release of her third studio album, Familia, in April last year.
