EAST RUTHERFORD, New Jersey -- At the Izod Center on Saturday (May 16), fans gathered for a night filled with pop music from [artist id="1231768"]Kelly Clarkson[/artist], [artist id="1801883"]Ciara[/artist], [artist id="1624630"]Jesse McCartney[/artist] and the [artist id="30064"]Black Eyed Peas[/artist], rock from the [artist id="1231961"]All American Rejects[/artist] and hip-hop from [artist id="2814953"]Soulja Boy Tell'Em[/artist].

Hometown boy Jesse McCartney got the party started with "Leavin'," but it was when he took off his sunglasses and sang "Beautiful Soul" that the sing-along really began. Jesse slowed it down for "It's Over," which he called his favorite song off his album depature. But it was clear the fan fave was [article id="1605018"]"How Do You Sleep?"[/article]

Soulja Boy Tell'Em played a very short set, which included "Crank That" followed by "Turn My Swag On." Then he requested all cell phones out as he took off his shirt to perform "Kiss Me Thru the Phone."

"Gossip Girl" star Taylor Momsen surprised the crowd, coming out to introduce the All American Rejects — while also plugging her band, the Pretty Reckless. AAR rocked the show with "Dirty Little Secret." Lead singer Tyson Ritter wanted to hear everyone scream for "Swing, Swing," and he showed some love for kids in the cheap seats before "Move Along." Then he broke into a spoken-word version of [article id="1598008"]"Gives You Hell"[/article] before the band kicked in. After doing their new single, "The Wind Blows," Tyson did his best Nixon impression and walked out.

Ciara brought some girl power with ironically titled "Like a Boy." Then she showed everyone how limber she is by doing splits as she went into "Goodies." Unfortunately, her [article id="1611423"]"Love Sex Magic" collaboration was left Justin Timberlake-less[/article], but the sexy moves she performed along with her dancers (which included a Lady Gaga lookalike) more than made up for it.

Keeping the girl power alive, Kelly Clarkson's killer voice rocked the room with "Since U Been Gone." The set included lots of new songs off her new album, [article id="1606168"]All I Ever Wanted,[/article] peppered with older hits, like "Miss Independent." Before [article id="1609587"]"I Do Not Hook Up,"[/article] Kelly listed her exceptions to that rule: Hugh Jackman and Russell Crowe. "Walk Away," "Already Gone" and "If I Can't Have You" also were fan favorites leading up to her finale "My Life Would Suck Without You."

Sean Paul graced the stage to introduce Flo Rida, who then made everyone dance to "In the Ayer." Flo asked the crowd to sing along for "Jump." He brought some female fans onstage for "the record that made him international," "Low," and dedicated "Right Round" to all the single ladies.

The Black Eyed Peas were the night's final act. Their set was filled with hits like "Don't Phunk With My Heart" and "Let's Get It Started." Their theme of the night was all about finding the party people in the house, and "Pump It" helped in the search. After determining the "Humps" were controlling the room, they sang that song. Calling their L.A. crowd at last week's [article id="1611037"]Wango Tango[/article] "wiggity wiggity wack," the Peas dedicated "Where Is the Love?" to the room, just before bringing the "Boom Boom Pow.
