The Backstreet Boys have been enjoying a resurgence of popularity these past few years thanks to their successful Las Vegas residency, as well as showing up on super popular shows like The Bachelor. And now, they鈥檝e been featured on Florida Georgia Line鈥檚 new single 鈥淕od, Your Mama and Me鈥 that allowed them to snag an invite to this year鈥檚 Academy of Country Music Awards.

And while Tim McGraw may have stunned the crowd last night when he took the stage with his love, Faith Hill, to perform the first single from their upcoming joint album, he unabashedly switched from performer to fan when the Backstreet Boys showed up.

With the grown-up boy band thrilling the crowd with an on-point performance of their classic 鈥淓verybody (Backstreet鈥檚 Back)鈥 along with taking on Florida Georgia Line鈥檚 single, the country music fans in the audience were totally into the tunes. And Tim McGraw? Well, he was downright OBSESSED! From the moment the Boys stepped out on stage, through every note and dance move, McGraw was on his feet LOVING it.

Seriously, his reaction was just as awesome as the performance itself.
