'So you liked it,' said host Ryan Seacrest, 49.
'We rushed the stage,' Katy said.
'Everything stayed on, you didn't lose any clothing,' Luke quipped after Katy earlier this season suffered a wardrobe malfunction following a performance.
'Three words – wow, wow, wow,' Lionel said.
Kayko was just one of the Top 12 contestants who competed to move on and make it to the Top 10.
The show also featured some star-studded moments including David Archuleta, 33, returning to the Idol stage to perform his new single Hell Together, a song that was inspired by his mother.
Ryan asked him to tell the story behind his song.
'I grew up very much in my faith and religion, very devout,' David said. 'But I came out of the closet a couple of years ago. It was very hard to balance faith and coming out. It was too much and so I stepped away and I announced it and I didn't hear from my Mom for a few days. So I was like ''oh no I pissed my Mom off''.'
