Justin Bieber may have been caught smoking weed again.

TMZ posted an Instagram photo of the megastar sitting at a table wearing a long chain necklace, a black backwards hat, and holding what appears to be a long joint. In the photo, Bieber is sitting next to a young woman who looks very similar to his rumored love interest, Ariana Grande.

Bieber and Grande’s camp reject the authenticity of the photograph. They claim that girl in the photo is not Grande and the picture has been photoshopped. However, TMZ’s art department argues that the light source in the photo is consistent and there is no evidence that the photo has been altered.

This photo isn’t the first time Bieber’s been caught lighting up. Back in January, the pop singer was photographed at a Newport Beach party with what looked like another joint in his hand.

Then in February, the 19-year-old was caught and apologized for smoking weed during his hosting gig on Saturday Night Live.

Adding to further speculation, Miley Cyrus, a self-professed advocate of weed, tweeted a picture of herself in a “Reefer Fever” shirt on Monday. The tank top features Bieber’s face with a joint in his mouth.
