It was the most talked-about moment of the night at the 2015 Billboard Latin Music Awards — Jennifer Lopez onstage, singing a medley of Selena Quintanilla’s most beloved hits, including “Como la Flor,” “Bidi Bidi Bom Bom,” “No Me Queda Mas,” and “I Could Fall in Love,” dressed in a pale pink ensemble reminiscent of the late queen of Tejano music. The heartfelt performance came 18 years after Lopez’s indelible portrayal of Selena made her a household name. Backed by the original Los Dinos band — made up of Selena’s brother A.B. Quintanilla, sister Suzette Quintanilla-Arriaga, and widower Chris Perez – JLo delivered an emotional tribute to an icon whose influence is still felt, 20 years after her life was tragically cut short.

After the performance, the Quintanilla family opened up to Billboard about how it felt to be a part of such a special moment, where the idea for the tribute came from, and how they’re keeping Selena’s legacy alive.

“I loved that she incorporated three of Selena’s main looks — the bustier, the high-waisted pant, and the ruffles,” said Suzette, giggling.

A.B. commented on just how good Lopez sounded. “When she held that last note on ‘No Me Queda Mas’ it was amazing,” he said. “The electricity was there and even though she was singing Selena’s songs, she made them her own tonight. She did a beautiful job.”

“From her heart — this is something that she really wanted to do,” added A.B.
