Rihanna reportedly had a box of her favourite crisps flown over from America to Britain.

The 'We Found Love' singer is said to be such a fan of Cheetos - an American cheesy snack - that she couldn't be without them while carrying out a promotional tour in London.

But according to reports, the box didn't arrive and staff at her five-star hotel decided to use bags of British cheese-flavoured crisps Wotsits instead.

A source told the Daily Star: ''Everyone was panicking when the box didn't turn up.

''We decided to sneakily empty bags of Wotsits into bowls around her suite and hope she wouldn't taste the difference.

''We were a bit nervous, but she ate them and didn't say a word.''

Meanwhile, a source had claimed the Rihanna's recent collaboration with ex-boyfriend Chris Brown - who she split with after her assaulted her in 2009 - was no meant to shock.

The insider told More! magazine: ''She'll have recorded with Chris not to shock but to remind the world that he's paid his dues and moved on, and that he's a very talented singer.

''I think she feels strongly that one bad moment in his life should not define who he is forever.''
