It was all about Jennifer López on American Idol, as three of the five male contenders closed their performances by singing inches away from her face -- and one even went in for a kiss.

Casey Abrams, Stefano Langone and James Durbin gave the most beautiful woman in the world, according to People Magazine, a lot of love. Casey took it one step further and gave J.Lo a tender smooch.

"Casey has soft lips," López joked about the Texas singer, who boldly (and quickly) gave a peck to the Puerto Rican beauty. “See now, Casey’s not playing fair.”

Not far behind Casey Abrams was Stefano Langone, the contestants' pick for the group's biggest flirt.

Wearing a T-shirt that outlined the cut of his muscles, Langone, 22, bumped and grinned -- literally! -- to NeYo's "Closer."

"Speaking for all the ladies here, it was very good," López told Langone with a smile. "You did a good job, baby!"

Stealing J.Lo's breath, musically at least, was rock-and-roller James Durbin, who put on what López called "the best performance of the night."

As his shadow emerged from the back doors of the studio, a marching band trailed behind him, Durbin rocked out to Muse's "Victorious."

“That was the highest we’ve ever heard you sing," said an impressed J.Lo.

The other judges, Randy Jackson and Steven Tyler, agreed with López.

Durbin hit his signature high notes and stared at López as he flung the mic stand.

“I'm going to go on a limb here with Jennifer,” said Jackson. “Dude you are unbelievable… probably the best performance we will see tonight!”

“I love that you are out of your mind, beautifully so,” added Tyler.

Still, the judges urged the contestants, including Durbin, to "really bring it" next week. The competition is still up in the air.

"Who's going to win?" López asked as the show came to a close. "I don't know!”
