Justin Bieber throws long term pals Lil Twist and Lil Za out of his home after his expensive jewellery was stolen

Some of Justin Bieber's very expensive jewellery has reportedly gone missing from his Calabasas, California, home.

And the 19-year-old is said to have blamed his friends Lil Twist and Lil Za for the theft as the pair were house sitting when the items first disappeared.

Upon discovering the apparent robbery, the troubled pop star is alleged to have kicked the two brothers out of his home and his entourage.

On Tuesday, Justin attempted to scotch the rumours of theft with a post on Instagram stating: 'Don't listen to em. I still got all my jewelry. (sic)'

But the posting, according to TMZ, disappeared less than a half hour later.

Lil Twist, 20, and Lil Za, 17, were occupying the teen idol's Southern California home while he was touring around the world to promote his Believe album.

The pair, who share the moniker of 'Lil', are said to have thrown quite a few parties in the star's absence.

While Justin had no way of ascertaining who stole his jewellery, he blamed his friends for allowing the theft to happen under their vigil – leading him to take action and kick the duo out for good.

Lil Twist and Lil Za are reported to be furious about the situation and unwilling to take the blame for the missing items.
