American Idol Crowns a Winner

The 14th season of American Idol came to a close Wednesday night, crowning pop rocker Nick Fradiani as its winner over Christian crooner Clark Beckham. But just as much as the finale was about selecting an Idol, it was also about throwing a big ol' party. Current hitmakers including Andy Grammer and Echosmith swung by for some celebratory performances featuring the season's contestants, as did novelty favorites like Ricky Martin and New Kids on the Block. These eight moments were the best of the night:

Fall Out Boy goes on for "Centuries"

The night opened with a bang as Clark and Nick joined Fall Out Boy for a rendition of the band's current smash, "Centuries." The poignant lyric "But you will remember me, remember me for centuries!" was the perfect plea for two young men on the brink of fame.

Ricky Martin lives a crazy life

Throwback favorite Ricky Martin took to the stage in a snazzy suit to perform his new single, "Mr. Put it Down," but thankfully soon removed his jacket to get down and dirty alongside the show's top five guys in a medley of his hits: "Livin' La Vida Loca," "She Bangs," and "The Cup of Life." Eliminated contestants Qaasim Middleton, Quentin Alexander, and Rayvon Owen looked to be having a ball as they joined in on the throwback performance, but it was the visible terror on the faces of the two finalists, Clark and Nick, that made it so much fun.

J. Lo backs it up

Jennifer Lopez took a break from her judging duties to join pals Pitbull and Prince Royce for the bilingual summer jam, "Back It Up." If this didn't make you want to throw on a bikini and sip a fancy frozen cocktail, nothing will.

Echosmith welcomes a new cool kid

Echosmith, the alt-pop group that broke out last year by teaching us all about "Cool Kids," welcomed purple-haired Joey Cook to sing along on their hit. Front lady Sydney Sierota seemed the quintessential role model for Cook's future.

Jamie Foxx keeps it simple

Rayvon Owen got the chance of a lifetime when Jamie Foxx invited him to duet on his new ballad, "In Love By Now." Sometimes all you need is two dudes with pretty voices and a piano.

New Kids on the Block teach the ropes

Sixteen-year-old Daniel Seavey got his boy band on, joining New Kids on the Block for vocals—and classic choreography—on the fellas' tracks "Step by Step" and "You've Got It (The Right Stuff)." Is One Direction hiring?

Andy Grammer meets his match

Previously known for his 2011 hit, "Keep Your Head Up," Grammer has topped himself this year with the sweet rising hit, "Honey, I'm Good." Nick Fradiani hopped on the song, as well as Grammer's "Back Home," for a delightfully gleeful performance.

The judges bring it home

Jennifer Lopez whipped out her sparkliest gown to cover Rihanna's "Diamonds" that led into a high-octane team-up with her fellow judges Harry Connick, Jr. and Keith Urban on Bruno Mars' "Locked Out of Heaven." But the best part? Urban's proud wife Nicole Kidman whooping it up in the audience.
