Lethal Bizzle has warned Justin Bieber to keep away from the name 'Bizzle'.

The 19-year-old Canadian confused fans recently when he changed his Instagram name to Bizzle.

It was speculated that the term could been used as a rap moniker.

However, it seems British rapper Lethal Bizzle isn't to keen on Bieber using the name.

He uploaded a photo onto Facebook of a news story about the singer's name, his own face and the text 'Leaave It yeah'.

Bieber, however, recently told a fan that the name change was only "for now".
