Jennifer Lopez’s ex-boyfriend and high school sweetheart David Cruz has died, the New York City Office of Chief Medical Examiner confirmed to Fox News on Monday. He was 51.

According to TMZ, he died on Saturday of heart disease.

Cruz dated Lopez for a decade after the former pair connected when the pop music superstar was just 15 years old and stayed with her through the mid-1990s until she landed her breakout role in “Selena," per People magazine.

He had been by Lopez’s side during many industry events during his time with the actress and singer and even accompanied her to the “Money Train” film premiere back in November 1995 and was said to be a movie production assistant at the time, according to an article published by People around the time of the film’s taping.

Per TMZ, who first reported the death, Cruz is survived by his partner of 18 years, Isa, who described him to the outlet as “kind and loving.”

"He never held on to anything and was always very open,” Isa said. “He was a devoted father, he helped raise his stepson who is now in the Marines. He loved the Yankees and Knicks. He loved going to the theatre with me. My favorite moment was family date night, because it wasn't just special for me but for the kids as well. He always made sure to end things with an 'I love you.'"
