Camila Cabello is up to something.

Yesterday, the pop starlet shared an animatronic video on her socials, in which a flying key literally unlocks her mechanised heart.

The video also includes the following text, "You are cordially invited to experience the first installment on September 5, 2019. Truly surrender to the drama. Courtesy of Camila Cabello". Besides the diegetic sound, there is no background music. The existence of the clip and the fact that the full reveal is only three days away, has led to speculation that she is poised to release new music.

In 2018, Cabello released her debut self-titled album and had her name on a number of the year's biggest hits, including the Young Thug–featuring 'Havana', which became Spotify's most-streamed song ever by a solo female artist in September that year, with more than one billion streams at the time.

Earlier this year, Cabello featured on Ed Sheeran's recent album of collaborations, No. 6 Collaborations Project, on the song 'South of the Border', with Cardi B.
