American Idol contestant Dalton Rapattoni has a new superfan!

The 19-year-old performer killed it on Wednesday with a soulful, powerful reimagining of the Billy Idol classic "Rebel Yell," and judge Jennifer Lopez was clearly crushing on the impressive singer.

As Rapattoni ruled the stage, it was clear Lopez was enraptured by his presence and his powerful voice, as she gazed into his eyes and silently mouthed the iconic lyrics as he sang them.

When Rapattoni wrapped up his number, the 46-year-old pop diva was blown away and could barely collect her thoughts long enough to critique the song.

"I don't care about anything, except that made me feel some...THING!" Lopez said, struggling to find the words she was looking for. "First of all, you're pretty as can be. I can't, with him. He's so pretty. I wanna squeeze you're little face and just…ugh!"

"Beyond that, it was a great performance," she added. "From here, I loved it."

As fellow judges Keith Urban and Harry Connick Jr. heaped praise on Rapattoni's performance, Lopez could be heard loudly agreeing and seconding their positive feedback. And as the judges prepared to move on to other contestants, Lopez couldn't help but scream out "sexy"!

Clearly, Rapattoni has a big fan in his corner.

Last week, the judges flipped out over La'Porsha Renae's amazing cover of the Tina Turner hit "Proud Mary." Check out the video to hear the powerful performance and the judges' glowing feedback.
