Songfacts®:

• "1,2, 3," is a fun song about an encounter with a guy that leads to love. The upbeat track contains English and Spanish lyrics and blends Latin, pop and urban vibes.
• Mexican singer-songwriter Sofia Reyes originally wrote "1, 2, 3" in Spanish with her best friend Nicole Zignago back in 2016. They then came up with different English and Spanglish versions. Reyes' manager, Charlie Guerrero, who was part of the session as well, suggested getting Jason Derulo on the song. He played it to the American pop star, who agreed to cut some vocals. Then they decided they needed some rapping to add strength to the track, and Puerto Rican rapper De La Ghetto agreed to jump on it.
