She and fellow X Factor judge Tulisa Contostavlos were reportedly unhappy about the five minute walk at Manchester's EventCity, moaning that it took 'too long'.
According to The Mirror, the pair started complaining after Tulisa, 22, hurt her feet in high heels and Kelly Rowland, 30, had to wear flats.
A source told the newspaper, 'They kicked up a big fuss because they don't want to walk very far in designer heels.
'It shouldn't have been a problem, but now two buggies have been drafted in, complete with X Factor branding, just for them.
'There had been no big egos or problems, but this could be the start of things as they now realise they can get what they want.'
