Warning!!! Justin Bieber: If you're going to wear trousers that low... make sure your pants aren't a girly shade of pink!

Justin Bieber is very much the teen idol no doubt.

And he's not afraid to show his metrosexual side - having already released nail polish and perfume ranges.

The millionaire popstar was spotted out with his dog Baylor and as he turned around, revealed an expanse of his underwear in his low-riding trousers.

The 17-year-old sported the pink underwear as he walked his dog in girlfriend Selena Gomez's neighbourhood.

Note to Justin Bieber: If you're going to wear your trousers that low... make sure your pants aren't a girly shade of pink!

Not a good look!

That is hideous looking!And pull your pants up please!
