Justin Bieber continued his 2013 Questionable Behavior Tour yesterday, April 16, when he posted a cartoon of himself in bed with a shirtless fan.

The Biebs posted the photo on Instagram with no comment, so it's not immediately clear if this is an artist's rendering of him with Anne Frank or what.

Maybe the girl is a metaphor for his monkey. (We may be reading too much into this.)

But considering the average Belieber is around 12 or so, the drawing has certainly raised some eyebrows.

It is in line with the rest of his Instagram offerings, though. On April 15 he posted not one, but two unnecessary shirtless photos on the site.

Here's hoping this doesn't lead to some type of erotic Justin Bieber animated series.
