Justin Bieber has raised eyebrows after posting online a cartoon of himself lying in bed topless with a female fan.

The singer uploaded the image on his Instagram and the move instantly created buzz among his numerous fans.

The cartoon sees a man with the name 'Justin' next to his head lying with a female 'Belieber' on his chest.

Both appear to be naked, or at least topless - and it's caused a stir within his fan base. One user commented:

"This basically means Justin would f**k a fan! Omg me please!"

Another Belieber meanwhile said: "OMG honey you're so sweet, it is impossible to hate you how can a person be hater while you're sharing pictures like this baby i love you hope you notice me some day and hope this picture will come true one day."

The post, however, did cause some concern due to the often young nature of Bieber's fans. Watch Justin Bieber perform live below:
