Backstreet is really back, alright!

All five original members of Backstreet Boys -- Nick Carter, Howie Dorough, Brian Littrell, AJ McLean and Kevin Richardson - have reunited and will release the new album 'In a World Like This' on July 30.

The band performed the new song 'Permanent Stain' on 'GMA,' which you can view below. It's pretty, catchy and full of harmonizing.

The Boys are further celebrating their 20th anniversary with a headline tour beginning Aug. 2 in Chicago. Tickets go on sale Friday, May 17. To show their appreciation for Backstreeters, the Boys will be giving away a free download of 'Permanent Stain' with the purchase of tickets to their upcoming U.S. tour. That's a two-fer you can't beat.

Jesse McCartney, who has been MIA from music for the past two years, and DJ Pauly D of 'Jersey Shore' will open the trek.

Go ahead, ladies of all ages and generations. Scream 'til your throat is red and raw.
