Rihanna was reportedly "panicking" after her production truck was stopped again.

The 'Stay' hitmaker's 'Diamonds' world tour has taken another twist just days after her buses were stopped at the border between Michigan and Canada on Monday night (25.03.13)

It caused a delay for her show in Winnipeg, and an insider has revealed Rihanna's reaction to the drama.

They told Hollywoodlife.com: "All her s**t, like her entire stage equipment, everything is on that damn truck.

"She at the f**king venue now trying to see what's going on. She's p***ed and panicking."

When the original trucks were stopped last week, a small amount of marijuana was found, although the source added this was not the case with this latest drama.

They said: "Ain't no f**king weed on her or her bus."

And although Rihanna wasn't on the trucks either time, she did post her own thoughts on the latest incident on Twitter.

She wrote: "They held my trucks at the border! This is not a good look for Winnipeg! My stage is in those trucks, disassembled.

"This means, the entire production could potentially start at a later time ... My bus and I are at the venue! Still no trucks!"
