Good girl gone bad Rihanna is in hot water with one of London's swankiest hotel.

The 23-year-old pop star reportedly forgot to turn off the water in her ($3,100) £2,000 a night suite at The Savoy in central London, flooding her rooms and leaving the carpets a soggy mess.

The drama unfolded last Sunday night after The Barbadian beauty ­appeared on ITV1’s X Factor.

A Hotel spokesman remained mum and would only say: 'We are unable to comment on the guests staying in our hotel.'

But hotel insiders were more than willing to speak out.

A source told People: 'The room where Rihanna was with her entourage flooded when the bath taps were left on.

'They all left the room and when they came back the carpets were wet through. There was no lasting damage but it took a while to dry out. All of the party were hugely apologetic.

'They were told not to worry. People at the hotel were joking that those in the floor below would need umbrellas – just like Rihanna’s song in 2007,' the source added.

The Savoy is popular with celebrities including Victoria Beckham and Elton John.
