A nude photo of Justin Bieber holding a guitar surfaced on the Internet on Monday.

The guitar is strategically held in such a way as so to prevent the pop star from completely exposing himself to the camera. Bieber's grandmother is featured in one of the photos, in which he reportedly played her a song while in the nude, according to TMZ. The photo was taken at her Toronto home during Canadian Thanksgiving in 2012.

The pop star reportedly spent the holiday at his grandmother's house and thought it would be funny to play a prank on his family, who had gathered at the home. Bieber's family thought his prank was quite funny, according to TMZ.

The photo, however, will undoubtedly fuel the scrutiny the 19-year-old has faced in recent months. From spitting off the balcony of a Toronto hotel in late July to kicking a member of paparazzi back in June, Bieber's alleged missteps have played out for the public to see.

The pop star has even drawn the ire of several celebrities, including former NFL receiver Keyshawn Johnson, who allegedly confronted the teen for speeding through their gated Calabasas, CA community in a Ferrari back in June.

Fellow teen star Miley Cyrus said she gave Bieber advice about his recent behavior.

"I told Justin to take a bit of time out," Cyrus told Britain's The Sun. "He's still stupid...but everyone does dumb stuff when they are messed up, and he's done dumb stuff. If it was your friend pissing into a mop box then you would be laughing, but because it's Justin Bieber, then it's really bad."
