Justin Bieber Turfs Out Lil Twist, Lil Za Over Trust Issues

Justin Bieber has allegedly thrown Young Money rapper Lil Twist and Lil Za out of his Calabasas, CA, home after jewelry and other items allegedly went missing from his home.

According to TMZ, the teen star discovered the disappearances earlier this month and blamed his house guests because the loss took place "on their watch."

Lil Twist and Lil Za --- their real names are Xavier Smith and Christopher Lynn Moore respectively --- have been staying at Bieber's house for some time, reportedly throwing parties while the singer was away touring.

The website reports sources close to the Canadian star say it's not known who took the jewelry or how much was taken, and that the singer doesn't necessarily think his friends took the goods.

Nevertheless, it's alleged Justin has told his two former house-sitters they can't stay at his house any more.

In addition, Gossip Cop reports an insider informed them Bieber is "having issues" with Lil Za and Lil Twist.

Into the mix of this developing story, just over two hours after TMZ went to press, the "Baby" star posted an Instagram of a black screen, captioned:

"Don't listen to em I still got all my jewelry."

That Instagram, which can be seen here, was deleted around 30 minutes later.

However, TMZ insist the theft occurred and stated on their website that Bieber is "lying to cover for his 'friends.'"

News of the alleged theft comes after previous reports that the pop star's manager, Scooter Braun, has been arguing with the singer about Lil Twist and Lil Za's continued presence at his home.

Last month Radar Online reported an insider said, "Scooter's cleaning house, and it starts with Lil Twist and Lil Za," with the source adding alternative living arrangements had been found for the pair.

Previously described by Justin as his "best friend" in an April interview with Teen Vogue, Twist has been accused of introducing the teen star to drugs. The Dallas rapper has also been involved in multiple traffic violations or accidents while driving Bieber's cars.

In August, Lil Twist was accused of battery by a woman during a party being held at Justin's house while the singer was away on his Believe tour. The Young Money rapper has denied the claims.

Lil Za has also been accused of drug-taking, and abusive behavior to a Calabasas resident in an alleged speeding incident while driving one of Bieber's cars. The altercation was captured on film.

It remains to be seen whether Za and Twist are seen at Bieber's home indicating all is forgiven, or whether there really has been a drastic change in the singer's living situation and inner circle.

Meanwhile, Justin is set to play Bangkok, Thailand's Challenger Hall tomorrow before moving on to further Asian dates and the remainder of his 15-month trek which wraps in Australia December 8.

The singer performed at the closing party for the Formula One Singapore Grand Prix on Monday, with pre-arrangements made for 30 concert tickets to be given to children from a local orphanage.
