Jennifer Lopez referred to her daughter Emme Maribel Muniz as "they/them/they're" pronouns while introducing the 14-year-old at the Dodgers Foundation's Blue Diamond Gala on Thursday in Los Angeles.

The audience laughed as Lopez referred to her singular child in the plural.

"I ask them to sing with me all the time but they won't, so this is a very special occasion, because they're very, very busy and booked and pricey," Lopez joked. "They cost me when they come out."

Lopez and Emme thrilled fans with a duet of Christina Perri's "A Thousand Years."

Emme rocked a hot pink shirt and shorts with a black baseball cap turned backwards and matching shoes, while mom wore a turquoise set and a feathered robe.

Lopez and Anthony divorced in 2014. They also share 14-year-old Maximilian, who is Emme's twin brother.

Emme and Max have half siblings named Cristian, Ryan, Ariana, and Chase.
