Rihanna tour stopped at Canadian border for second time in a week

A$AP Rocky is not the only American musician who has a rocky relationship with Canada's border guards -- Rihanna isn't too happy with them either.

For the second time in the past week, the 25-year-old singer's tour was held up at the Canada-U.S. border on Monday morning, this time in Winnipeg.

In a series of tweets ahead of her Diamonds World Tour gig in Manitoba's capital city last night, RiRi seemed to get increasingly concerned about the delay.

"This is not a good look for Winnipeg!" she tweeted. "My stage is in those trucks, disassembled! #DiamondsWorldTour"

RiRi's tour buses had already been stopped once before in Detroit on Wednesday trying to get into Windsor. Customs reportedly gave the buses a second inspection after smelling marijuana on board and drug-sniffing dogs discovered one of the tour passengers was holding a small amount of chronic. The culprit was given a penalty.

Winnipeg fans were warned on Monday night that RiRi's gig would start late due to the border incident. When the songstress finally came on stage, reportedly 90 minutes late, according to the Winnipeg Free Press she shouted to the crowd, "I just want everybody to say, ‘F--- customs.'"

And it seems that despite her previous comments about the city, she didn't hold it against her fans.

"It’s 11 o’clock at night… every last one of you showed up, and you stayed, you make this s—-- possible," she said. "Thank you so much, I love you… Winnipeg’s always so special to me."

Hopefully her trip back across the border won't be so "special."
