TORONTO - R&B/pop singer Keshia Chante and country star Tara Oram have signed on as judges and mentors for the upcoming season of YTV's talent show "The Next Star."

Record label executive Mark Spicoluk will also be on the judging panel for season 5 of the show, which YTV says is its top-rated series.

Hosted by Adamo Ruggiero of "Degrassi: The Next Generation" fame, "The Next Star" sees Canadian singers ages 15 and under vying to become "Canada's next singing sensation."

Previous contestants have included Ontario-based Alyssa Reid, who was recently nominated for a Juno Award for new artist of the year.

Last season's judges were singer Suzie McNeil, music marketing veteran Steve Cranwell and songwriter and former MuchMusic VJ Christopher Ward.

A six-city, cross-Canada audition tour for season 5 of "The Next Star" begins April 28 in Halifax. The new season is due to premiere this summer.
