Nickelodeon's 2015 Annual Kid's Choice Awards are just three weeks away and Nick Jonas, who was announced as the show's host in February, will be joined by some powerhouse musical acts. Aussie pop-punk group 5 Seconds of Summer, Iggy Azalea and Jennifer Hudson will be sharing the stage with the "Chains" singer on March 28.

5 Seconds of Summer, who are up for Favorite New Artist, told People magazine, "We are so excited to be nominated and perform at the Kids' Choice Awards!"  Hot off the plane from Japan after supporting One Direction in Osaka and Tokyo, we're betting on the 5SOS boys to bring some killer energy to show. The real question is: What color will Michael Clifford's hair be?

Iggy Azalea is up for both Favorite New Artist and Favorite Song of Year (for "Fancy" and "Problem"). She'll be joined by none other than - you guessed it - Jennifer Hudson. The motley duo will perform their addictive single "Trouble."

Don't worry, Nick lovers, the youngest Jonas Brother will be working overtime. In addition to hosting, he's set to open the awards show with a performance of his hit single "Jealous." Prepare to swoon. The KCAs are bound to be buzzing, so tune in on Nickelodeon at 8PM ET on March 28 to catch the whole shebang. Voting is still open on the KCAs website, so you can still cast your vote for your Favorite Book and Most Addictive Game. Candy Crush, anyone?
