Justin Bieber and Chris Brown are among the mega-stars scheduled to appear on the 'Today' Show's weekly Summer Concert Series at Rockefeller Plaza in New York City in the coming months.

As reported by Idolator, Usher will kick off the series on May 18 to promote his upcoming album, 'Looking for Myself.' Rapper Pitbull performs the following week, while the yet-to-be-determined  'American Idol' winner and runner-up will appear on a rare Thursday edition of the concert series on May 31.

Bieber and Brown highlight a huge June. Though his 'Fortune' album has been delayed until July, Breezy will grace the NBC stage on June 8. The Biebs will promote his 'Believe' album a week later before what is likely to be a raucous audience. We wonder how many days in advance people will start camping out for that one!

Flo Rida and Hot Chelle Rae take the stage in July, and following a break for the Summer Olympics, Train and Jason Mraz with Christina Perri close out the concert series in August.
