Justin Bieber and Carly Rae Jepsen, both under the guidance of talent manager Scooter Braun, dominate the nomination list of the 2013 Juno Awards, earning the most nods with four and five respectively. Both artists are pitted against each other in all the four categories that Bieber was nominated in, with only Jepsen's Single of the Year nod for "Call Me Maybe" putting the "Canadian Idol" alum at the top of the list.

Both Bieber and Jepsen are vying for Artist of the Year as well as the Juno Fan Choice Award. His "Believe" album and her "Kiss" studio effort are both up for Album of the Year and Pop Album of the year honors.

Jepsen along with Canadian rockers Marianas Trench and Billy Talent have been included in the line-up of performers for the event, with many more to be announced in the weeks to come. Marianas Trench is going up against Bieber and Jepsen for the Album of the Year award for their studio set "Ever After", while Billy Talent's "Viking Death March" is among the contenders for Single of the Year together with Jepsen's "Call Me Maybe".

The 2013 Juno Awards, honoring the best in Canadian and international music, will be telecast from the Brandt Center in Regina, Saskatchewan on April 21. Standards crooner and Canada native Michael Buble will host this year's ceremonies. On that night, the Juno Awards will also honor k.d. lang with an induction into the Canadian Music Hall of Fame.
