And now for something completely...predictable

Justin Bieber has pulled the plug on a big event in Montreal Saturday, but only after the handwriting was on the wall -- the promoter wasn't paying him...

Bieber was scheduled to host an event at Beachclub, where he'd sing one or 2 songs and press the flesh. It's the same club where Kylie Jenner celebrated her 18th birthday and raked in $200K...(A)ccording to the contract Bieber's team signed with the promoter, they would pay Justin 1/2 of his appearance fee when the contract was signed and the other half 2 days before the event. We're told the contract was for "a couple of hundred thousand dollars."

We're told Justin got the first half but Thursday came and went but the balance never showed. Our sources say Justin's people contacted the promoters and were promised payment pronto, but it didn't happen.

Our Justin sources say the promoter had gone off the radar...A rep for Beachclub tells TMZ, "We are incredibly disappointed and upset by the lack of professionalism exhibited by Team Productions (the event's promoter) in violating their contract with Justin Bieber and disappointing the thousands of fans that were going to flock to Beachclub today."

Roger Stone!!! Damn, but he pops up in the weirdest places!

Roger Stone, an adviser to Carl Paladino, marched in the gay pride parade that the New York gubernatorial candidate has called a “a terrible thing.”

His towel frontal pic here is from his Swinger advertisement during the Bob DOLE "Family Values" campaign, in which Rog asked for dudes to join him and Nikki in hot pursuits.

Roger Stone, the longtime Republican dirty-tricks operative...is financing, staffing, and orchestrating the presidential campaign of Reverend Al Sharpton...(They) are, in a sense, brothers under the skin, outlandish personalities too large to be bound by the constraints that govern the rest of us.

The hot rumor in New York political circles has Roger Stone, the longtime GOP activist, as the source for Dan Rather's dubious Texas Air National Guard "memos." Anyone ever heard of him?

The two clashed after Stone – known universally in political circles as a Nixon-era “dirty trickster” – helped bring down Trump friend and New York Gov. Eliot Spitzer in a prostitution scandal. But soon Stone and Trump were back and working together.
