 The Canadian pop star left fans waiting at his concert for more than an hour-and-a-half because he was playing a game of ping pong backstage with one of his dancers. 
 
 “Justin was completely engrossed in the game and couldn’t be bothered,” said a tour insider. 
 
 “He knew he was starting the concert late, but he just didn’t care.”

 Then, during a dinner date with with his on-again, off-again girlfriend Selena Gomez, Bieber stunned onlookers after refusing to tip his waiter. 
 
 The pair went to “a very upscale restaurant on Friday night for a free meal and even though the meal was complimentary, Justin couldn’t be bothered to tip the hard working waiter.” 
 
 Said our spy: “It was very low class and just disrespectful. Selena acted like a true lady, but Justin acted like an entitled punk.”

 Justin Bieber Pot Bust on Tour Bus 
 
 Exclusive Details 
 
 TMZ has spoken with a rep for the Stockholm PD, who told us ... Around 7:10 PM on Wednesday night, an officer smelled weed coming from Justin's bus, which was parked in front of the Grand Hotel. 
 
 
 
 Cops say ... when the bus left the hotel and headed toward the Globe Arena, the officer contacted a special narcotics unit, which issued a warrant to search Bieber's bus. 
 
 
 
 We're told cops searched the bus in the parking garage of the Globe Arena -- no one was on the bus at the time. 
 
 
 
 Cops say they found a small amount of narcotics (they won't say which drug, but local papers say it's weed) -- along with a taser. 
 
 
 
 We're told cops have not identified a suspect yet ... and the bus has not been impounded. 
 
 
 
 Bieber had been seen with his pal Lil Za in the hours before the weed incident ... and FYI, Za is the guy who was seen smoking pot with Bieber at an L.A. home earlier this year. 
 
 
 
 Cops tell us NO ONE WILL BE CHARGED because they have no idea who was in possession of the drug since the bus was empty. They found the narcotic on the floor of the bus so they have no clue who brought it on. 
 
 Story developing ... 
 
 
 
 
 
 is so rock n' roll -- his tour bus was raided by Swedish police who allegedly found marijuana on board Wednesday night ... according to a Swedish newspaper.Police reportedly boarded the bus in Stockholm as the bus pulled up at the arena where Bieber was performing ... and found a "small amount" of what appeared to be pot.A police spokesman told the Aftonbladet newspaper ... they first detected a "strong smell" of marijuana coming from the bus as they were controlling the huge crowd that had gathered outside Bieber's hotel.The Swedish report says police also found a stun gun ... which requires a permit.No arrests were made ... and it's unclear if Justin was on the bus, or if he'd already entered the arena, when the raid went down.
– Justin Bieber: not a huge fan of monkeys or his grandpa, but apparently a fan of marijuana. According to a Swedish newspaper report picked up by TMZ, Swedish police raided Bieber's tour bus last night after sniffing out a "strong smell" of pot wafting from it. They allegedly found just a small amount of the drug, per local papers. They also found, perhaps more oddly, a stun gun (which does require a permit, TMZ points out). Cops don't expect to bring charges, because no one was on the bus when they searched it, so they can't tie the alleged drugs to any one person. Another unflattering Bieber report from Denmark: Over the weekend, he's said to have shown up six hours late to a photo shoot at an Elizabeth Arden cosmetics store, where he then threw "a temper tantrum" and refused to wear the costume organizers wanted him in. "This kid is quickly is quickly getting a reputation as someone that no one wants to work with," a source tells Radar. "It was disgraceful." He then was reportedly an hour-and-a-half late to his concert ... because he was "engrossed" in a ping-pong game backstage.
