Madonna performed to a star-studded audience on the London leg of her Sticky + Sweet world tour on Thursday (11Sep08) - with Gwyneth Paltrow, Kate Hudson and Penelope Cruz all watching from the crowd.
The 50-year-old took to the stage at Wembley Stadium for her only gig in England and delighted the celebrity group - which also included Fergie from the Black Eyed Peas - with energetic dance routines that belied her age.
Madonna wowed the 90,000-strong audience by performing 22 of her hit songs, including classics Into The Groove, Vogue and Like A Prayer.
However, some of the spectators were left disappointed when sound problems made it difficult to hear the Material Girl's vocals.
Voicing their frustrations on an internet message board, one gig-goer said, "The sound was absolutely shocking. The speakers must have blown. You couldn't even hear Madonna. I've never seen so many people complaining outside the concert."
The tour concludes in Sao Paulo, Brazil on 21 December (08).
