Sometimes, a kiss is just a kiss.

Marc Anthony and Jennifer Lopez raised eyebrows Thursday when they locked lips moments after performing the duet "Olvidame y Pega la Vuelta" at the 2016 Latin Grammy Awards. The exes—who co-parent 8-year-old twins—have remained friendly in the five years since they called it quits, and Anthony is producing his ex-wife's Spanish album, slated for release in 2017.

Lopez presented Anthony with the Latin Recording Academy's Person of the Year award. "You are giving us classics that will remain with us forever," Lopez (speaking in Spanish) said to Anthony. "You will always be many things in my life—a mentor, a soulmate, a father. He is not only a Person of the Year—he is a living legend." The crowd chanted "kiss," so the stars obliged.
