Rihanna has reportedly paid £15,000 for an emergency haircut after hers was ruined in a sauna.
The We Found Love singer - who recently changed her red locks to blonde - apparently flew her stylist first class to London from Los Angeles to fix her matted tresses.
According to The Sun, the 24-year-old star had been for a swim at her hotel and used its steam room and sauna before disaster struck.
A source said: "When she got out, her hair was tangled and matted. She slapped a load of conditioner on but it didn't get through the mass."
With a TV appearance on The Jonathan Ross Show scheduled for the next day, Rihanna decided that stylist Ursula Stephen was the only woman for the job.
The insider added: "She didn't want to take the chance on an unknown.
"Because they were on such a tight schedule, they had to get her on the first flight. Rihanna didn't care about paying a fortune."
She was pictured yesterday (29.02.12) in London wearing a black cap in an apparent bid to hide the disaster.
The source explained: "Rihanna shoved a hat on to go to the studios. She was fine when she knew Ursula was on her way."
