Naked Justin Bieber pictures continue to spread, and this time, showing the teen pop sensation serenading his grandmum wearing nothing but his guitar strapped on. The nude pictures were shown in publications of The Star and The Sun.

The guitar was strategically positioned in the naked Justin Bieber picture, safely covering the private part of the singer heartthrob. Many called it as 'seranude' which took place in October 2012, according to The Sun's report. The young idol even took off with some lyrics like, "I love you Grandma. How are you?"

Bieber's grandmum may have not been moved by the pop singer's usual childish antics, but it is the reactions of many in the industry that make the naked Justin Bieber picture appear troublesome. For most, it became an incident gone wrong. Good thing that the grandmum begged the young crooner to eventually get back in the room to put some clothes on.

Last weekend, he almost suffered from a shameful wardrobe malfunction when his trousers were falling right around his ankles during one concert at Jacksonville, Florida. He tried desperately to make it appear that it was a new fashion style rather than a fashion fail.

Bieber was also seen handpicking cocktail waitresses using a flashlight who were even named by the New York Daily News. According to the publication, the two were sent from the South Pointe Club to accompany the young singer to his private home.

The 19-year-old crooner is under scrutiny of the public eye for his recent pranks, paparazzi shots, fashion fails or naked pictures. But the question is whether the majority still finds him funny or maybe too rude already to even be a model to the youth? Or maybe he's just another normal teenager going through the stages of growing up. Though it won't hurt to remind that sometimes it can be rude to be in nude.

If these naked Justin Bieber pictures won't step on anyone else's business, then let the boy grow up. But if it gets in the way of raising responsible youth through idolizing him, then it can be better if he'll start going slow on his naughty antics.
