"World of Dance" features solo and group performers as they compete for a grand prize of $1 million. Lopez, who started her career as a dancer, also executive produces the series."[The show is] the best thing I could have ever done," the star said at a press event in March. "It's like a dream come true and, like, the perfect job for me."
"I love dance at such at core level and I always consider myself a dancer first because I became a singer and an actress after. That was my first form of artistic expression. It's so part of who I am," she added.
The singer couldn't help but gush about the retired New York Yankees player on the May 4 episode of "The Late Late Show" with James Corden.
"He's the best. You would love him," she told host James Corden. "Honestly, he's a great guy. He's fun. He's awesome."
