He's looking a little giddy!

A glassy-eyed, shirtless Justin Bieber couldn't seem to get the words out when he decided to go viral with Instagram's brand new video feature.

"So crazy news," the 19-year-old pop star said before laughing it up. "Crazy news guys... there's video on Instagram."

Since posting the video, Twitter went wild with speculation that the star was stoned during the quarter-minute clip.

Hi(gh), Biebs!
