The sky-high bill came because Aniston insisted her hairdresser Chris McMillan accompany her on a week-long trip to Europe, the ‘Daily mail.co.uk’ reported.

He flew with Aniston from Los Angeles to London in first class last week, at an estimated cost of 14,400 pound.

McMillan was treated to an all-expenses-paid stay at several top hotels for the seven-day visit at a cost of 10,000 pound.

It is said that he charged up to 1,500 pounds a day for his expertise, pushing up the bill by another 10,500 pound. He also accompanied the Hollywood star on a private jet trip to Paris for a premiere of her latest film ‘Marley & Me’, racking up another 4,000 pound bill.

However, it is unclear whether McMillan, who is a close friend of Aniston, was paid personally by her or by the film's production company, Fox.

Earlier, the "Friends" actress revealed that her love of the natural look is not restricted to her hair.
