Jennifer Lopez made Macy’s annual fireworks event more exciting than ever on Independence Day.

Of course, she appeared very gorgeous in a sexy low-cut dress, making all eyes turn to her.

The singer took the stage to debut a new song in Spanish with the band Gente de Zona, titled “Knee to Knee”.

This song was not only well received by fans, but even her boyfriend, Alex Rodriguez, also liked it.

Before J Lo’s performance aired, A-Rod posted a cute video on Instagram just hours before. It’s no surprise that A-Rod loves his girlfriend’s new music.

In an interview with ET in April, JLo shared, “He heard the news. He loves it. He loves it. I’m so excited.

Every time I finish a project of some kind , I brought home for him to listen to and he was always wonderfully supportive.”

This only further proves Alex Rodriguez’s strong affection and support for Jennifer Lopez and her music career.

At the same time, it also highlights the passionate and happy relationship between the two.

Jennifer Lopez gave fans a taste of her new music on Tuesday, when she premiered her new single, “Ni Tu Ni Yo,” during Macy’s Fourth of July Fireworks Spectacular.

The pop superstar taped her performance several days prior to the live NBC special in New York City. She rocked a sexy black gown with shimmering gold and silver embellishments, which showed off her super toned legs with two waist-high slits.
