Part 1 of
American Idol's epic series finale on Wednesday saw some of the best performances of the season so far, but nothing was more jaw-dropping than judge Jennifer Lopez's flawless finale style.
The 46-year-old pop star stunned as she took the stage in a black, semi-sheer Zuhair Murad dress that hugged her hips and flowed around her Tamara Mellon heels.

The gorgeous gown was covered in sparkling beaded embellishments that gave Lopez the appearance of being covered in fireworks -- a fitting style for the bombastic occasion.
After the show, Lopez spoke with ET's Sophie Schillaci about the night's emotional performances by finalists
La'Porsha Renae and Trent Harmon.
"I can only imagine how [Renae] is feeling, all the emotions, getting to the finale, all the stuff she's overcome," Lopez shared. "Same with Trent. They're both two amazing people who have overcome a lot."

Lopez admitted that both contestant had "so much going for them," and that I would be a tough battle for the title of American Idol.
"They're so very different. They're both very privileged voices, they're both great storytellers when they sing. They have so much talent," Lopez gushed. "So you just have to vote for who you like."
The "Feel the Light" singer also talked about
her time on the show, and confessed that she couldn't choose a favorite memory from all the wonderful moments she's enjoyed.
"There's been so many," Lopez said. "I only planned to do this one season and I wound up doing it for five."

Idol’s star-studded grand finale on Thursday, Lopez is set to perform her new single, “Ain’t Your Mama,” a song she said is “very empowering.”
"Guys have this tendency, once they love you in the beginning and you're the hottest woman on Earth, and then all of a sudden, it's like, 'Okay... where's my food?' It's like, 'What!? Are you kidding me? Take me out! What are you doing right now?,’” Lopez explained.
"But it's a really fun song and everybody seems to be responding to it really well so I'm happy about that," she added.
Along with Lopez's performance,
will feature appearances by Idol's final night Idol alums Carrie Underwood, Kelly Clarkson, Jordin Sparks, Katharine McPhee and Kellie Pickler, among others. WATCH: 'American Idol' Finale: 15 Big Reveals From the Series Retrospective Related Gallery
