The talented singer-actress Selena Gomez is back, and this time she recruited Camilo for the breezy song "999." The song and its accompanying music video feature Gomez rocking a slew of coloured wigs and ensembles while roaming natural settings. Produced by Edgar Barrera and written by Camilo, the romantic pop track is about "someone who wants to give it their all, but resists at the very last stride, going against what their heart longs for," per the single's press release. "Camilo is a fantastic songwriter and singer who proudly wears his heart on his sleeve, which is something we connected on immediately," Gomez said about Camilo. "I couldn’t have been more excited to collaborate with him." Hours before the song's release, Camilo also shared an Instagram Story video of himself expressing what he admires most about Gomez, saying, "One of the things I admire most about Selena, is not only her talent and her career but also the relationship she has with her fans and her people." "999" follows Gomez's seven-track "Revelación" released March 12 via Interscope/IGA that marked the biggest week for a Latin album by a woman since 2017. The EP featured collabs with rising Latin acts Myke Towers and Rauw Alejandro.
