A spokesperson for Madonna has defended the singer's performance in London last night, which has come under attack by fans.

A large proportion of the pop stars fan base have criticised the sound quality of the concert at Wembley Stadium, while others have complained about Madonna's late arrival on stage.

In a statement to the London Paper, a spokesperson said: "Stage times are only guidelines. I was at the gig and the sound was fine."

Despite enjoying the concert, one fan told Gigwise that transport problems afterwards had “completely ruined” her evening.

The concert, the second of only two UK dates on the singer's Sticky & Sweet world tour, was watched by 90,000 people, including a host of celebrities.

The elaborate show featured four sections: 'Pimp', 'Old School', 'Gypsy' and 'Rave'.

Madonna, who will play a total of 27-dates, honoured her latest album, ‘Hard Candy’, during her two hour set.

But also played a number of tracks from her back catalogue, including ‘Vogue’ and ‘Music’.
