Mom's Back-To-School Dance To 'Bye Bye Bye' Is The Perfect Farewell (VIDEO)

Tracy Moutafis is not shy about expressing her back-to-school excitement. For five years, the mom of two has been posting a celebratory video of herself dancing as her kids' school bus pulls away. Her 2012 "Celebration" dance made her a bona fide Internet sensation, and now -- hooray! -- she's back with a new hilarious performance to *NSYNC.

Moutafis told GMA that she looks forward to "lots of mommy time" when her sons, George and Angelo, are no longer home for the summer. Bye bye bye, kids!
