TORONTO - Have faith, Beliebers: Justin Bieber says his new album will be out June 19.

"Believe" is Bieber's third full-length release and both prior albums -- 2010's "My World 2.0" and last year's Christmas disc "Under the Mistletoe" -- opened at No. 1 on the Canadian charts en route to multi-platinum sales.

Bieber revealed the news during an appearance on the reality singing competition "The Voice" on Tuesday night.

The 18-year-old Bieber sparred awkwardly with judge Adam Levine before making the announcement, while also pledging to return for the NBC show's season finale in the coming weeks.

He says he'll perform his new single, "Boyfriend," then. The song has topped the charts in Canada.

Host Carson Daly pressed Bieber on whether "Believe" could possibly be delayed, but the Stratford, Ont., native was firm in his response.

"I'm positive. I'm not going to change the date," he said.
