Melbourne, Nov 21 : Sexy singer Rihanna lost her cool and went on a F-word rant when her driver got three minutes late to pick her up outside a nightclub.

"She was with a massive entourage and one was on the phone asking where he was. Suddenly Rihanna started shouting in the face of this guy, saying, ''Where the f**k is my car?''" the Daily Telegraph quoted an insider as telling the Daily Star.

She added: "After another minute, she squawked, ''I mean it guys, you''ve now got 30 seconds to get me my car or someone is losing their employment. I f**king mean it, 10 seconds and I get nasty''."

The scene ended when the 21-year-old driver finally drove in.

"The driver was so panicked, he almost drove the wrong way down Piccadilly Circus," the source added. (ANI)
