Justin Bieber made his Instagram video debut by posting a clip of himself giggling uncontrollably, sparking rumors that he was high on drugs while shooting the video.

The 19-year-old singer's eyes appear glazed and he is shirtless in the first video that he uploaded on the photo-sharing site Thursday, the same day the new feature was launched.

The clip is captioned “Hahaha,” and Bieber appears to find it difficult to talk coherently, managing to say just a few words before he cracks up.

“So crazy news, guys, there’s video on Instagram!” the Canadian teen sensation said in the video that lasts for about 15 seconds.

The Instagram clip has since gone viral, garnering approximately 922,000 likes from Bieber fans.

This incident comes just days after musician Kid Rock said in an interview with GQ magazine that it was only a matter of time before Bieber found drugs and ruined his life.

"It's just a matter of time before someone puts a huge line of cocaine in front of Bieber and he's going to be like, 'Yes! This is f**king awesome!'"

Back in April, Swedish police found drugs on a tour bus used by Bieber during his Stockholm concert. Police spokesperson Lars Bystorm told Fox News at the time that a small quantity of drugs and a stun gun were found when officials raided the bus that was parked at the Globen concert venue in the Swedish capital.
