Rihanna has branded French people ''f***ing insane'' after nearly causing a riot in Paris.

The 24-year-old singer sparked ''absolute chaos'' when she posted the number of her Eurostar train and her arrival time at the Gare du Nord train station in the French capital city on twitter, which resulted in hundreds of screaming fans turning up to see their idol after her trip from London.

Following the frenzy on Saturday (01.09.12), Rihanna launched a foul-mouthed tirade on the social networking site against her ''out of control'' fans.

In a series of tweets, she wrote: ''The French are f***ing insane!!!

''FYI, if u push me, you WILL get pushed the phuck back! Papz and crazies included!!!!

''I just had to fight my way out of a damn train station!!! SMH

''Y'all are outta control with this s**t in Paris!!! (sic)''

Rihanna was later blasted by security chiefs at Gare du Nord for her ''utterly irresponsible'' behaviour.

A security chief at the station is quoted by The Sun newspaper as saying: ''It was absolute chaos, and all Rihanna's fault. What Rihanna did was utterly irresponsible.

''There was genuine fear among other people at the station.''
