ET's Cameron Mathison caught up with Lopez after her performance, where she revealed what it was like to work with Anthony again.
"I mean there's nobody better than him in Latin music," she said. "I am probably his biggest fan. Honestly, to have him work on the album with me was scary, because I thought, 'We're gonna fight,' but there is nobody else I would want to do music with."
Lopez added that the experience made their "relationship even better."
"We had a lot of fun together," she continued. "We connect on a certain level which is through music and so it was a great thing and I think it's all there on the album."
