The Saga Continues!Justin Bieber over the weekend when rap buddy Lil Twist allegedly 'Threatens'

Justin Bieber The 18-year-old was snapped dining at Crustaceans restaurant with the 'Rack City' star in Beverly Hills and a handful of his entourage called into the Best Buy electronics store in Southern California's San Fernando Valley on Sunday (Feb 3), but the excursion took an unexpected turn when a fan was threatened after taking a snap of Justin without his consent.

The pair tucked into Vietnamese food before heading off in separate cars, with Biebs being spotted jumping into his beloved white Lamborghini.While initial reports pointed the finger of blame at one of his security detail, it has since emerged that sidekick Lil Twist was the one issuing the warning.

“Justin Bieber asked people not to take photos without asking and said he would pose with anyone who wanted a pic,” an eyewitness told Radar Online. “(Twist) tried defending Justin and got in the guy's face and tried to take his phone.

"The guy tried to get away and Twist went after him. Witnesses were appalled at what was happening. Twist created a scene.”

“Justin Bieber guard identified himself as part of the security and calmly explained that no one wanted to take his phone,” added the eyewitness. “The guard calmed the situation after Twist made it a mess.”

The incident raises further concerns about Justin's association with Twist and comes just two days after another rap buddy, Lil Za, was pulled over while driving the 'Baby' singer's Ferrari without a licence.

Pictures of Justin Bieber smoking marijuana with Twist at a party in Newport Beach emerged on website TMZ last month, and according to sources the Bieber camp are growing increasingly concerned by his choice of friends.

“Then guy is not a good influence,” an insider said of Twist. “Justin Bieber needs to find a new friend.”

The Canadian singer is rumoured to have reconciled with his sweetheart Selena Gomez after sightings of the Wizards Of Waverly Place actress leaving his LA pad were obtained by X17 Online.

The on/off couple were also reported to have attended a concert together to see new girl group Young LA in concert.

While, last week Biebs also landed himself in more hot water after new photos of him smoking marijuana with yet another rapper pal, Lil Za, outside a luxury mansion in Los Angeles.
