The season finale of 'Glee' is just a week away, and Matthew Morrison has a new album to promote. So Morrison announced today on 'Good Morning America' that he will be joining the Backstreet Boys and New Kids on the Block tour this summer "playing some arenas and stuff."

The ever-supportive Robin Roberts seemed flabbergasted. "That is awesome," she cooed. "That is going to be wicked cool. Thank you for sharing that with us. Wow. Our minds are racing right now."

Yes, teen idols of yesteryear paired with a singing-teacher phenom of today; it's a lot to digest. Now all 'Glee' needs to do is cover 'Backstreet's Back' and 'The Right Stuff' and we will have really bridged the great generational divide.

Watch the announcement after the jump.
