The final 24 contestants on this season of American Idol can do a lot more than just carry a tune: the group can party!

On Friday, at the Day After Lounge in Hollywood, these finalists got together with Ryan Seacrest, Ace Young and Justin Guarini to celebrate their impressive feat. Guarini, at least, was quite impressed with the talent in the room:

"The judges have always been saying, 'this is the best year ever' and so on, but this year I really think they got it right," he told Us Weekly during the festivities.

Inside, the contestants posed for photos and flirted with each other, witnesses said.

Kady Malloy, for example was actually spotted holding hands with Colton Berry, the last person selected to advance to the finals.

Meanwhile, Kristy Lee Cook, known for her a capella rendition of "Amazing Grace" strutted around the room with a few girlfriends. Everyone had a good time.

The competition picks up again Tuesday night when the guys take the stage for a handful of live performances.
