Jennifer Lopez is having the best night ever.
The 47-year-old singer performed her new single, "Mirate," from her highly-anticipated new Spanish album, on Thursday during the Billboard Latin Music Awards in Miami, Florida.
Dressed in a sheer silver gown, Lopez took the stage with a live orchestra. Halfway through her emotional performance, fans vigorously cheered on the Shades of Blue star. But as it turns out, her biggest fan was her ex husband, Marc Anthony, who was the first to give her a standing ovation.

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."
Earlier in the night, Lopez won two Billboard Latin Music Awards, including Premio de la Estrella Award (Telemundo's Star Award) and Best Social Media.
"Everyone knows how much I love selfies," she told the crowd. "But what I love the most about social media is being able to communicate and connect directly with you, my fans."
"That truly excites me," she continued. "It makes me feel so much closer to you."
"Most importantly, let's remember to use our voices on social media to do good, to spread positive messages," she concluded.
