It was a big night, so what better way to unwind than a fancy Italian dinner?!

Jennifer Lopez was joined by Keith Urban and wife Nicole Kidman, as well as fellow judge Harry Connick Jr. and his wife Jill, for dinner at Osteria Mozza in West Hollywood last night, and we bet their party had a lot to discuss over their pasta! The trio of American Idol judges took the opportunity to all perform together on last night's finale, and they totally brought the house down!

J.Lo kicked off the mini concert by belting out her own version of Rihanna's "Diamonds," and then the country star and the jazz man chimed in with a rendition of Bruno Mars' "Locked Out of Heaven." The show ended with contestant Nick Fradini being crowned the winner of this season's competition.

There is only one more season left of the iconic program, and then Jenny from the Block heads to Las Vegas to start her residency! It's like the end of an era!
