Criss took the stage to play and sing 'Teenage Dream,' and many wondered if the star was drunk, BuzzFeed reports.

The actor went to his Twitter account to clear up the speculation.

"You know you've made it when the main discussion over one of your performances is whether or not you were drunk," he wrote, adding the hash tag "iwasactuallysleepwalking."
