The singer's gym-buddy (and fellow Anglophile) Gwyneth Paltrow was all smiles as she settled in to watch the Sticky and Sweet show next to fellow actress Kate Hudson. Also sitting nearby in London's massive Wembley Stadium: Fergie and Penelope Cruz.
In fact, Madonna, 50, had so many famous friends on hand, they filled not one, but two VIP areas.
Another all-star box included Nicole Kidman, who – like Cruz, Fergie and Hudson – is in London prepping for the upcoming movie-musical Nine. During the singer's athletic, 90-minute set, the Oscar-winner laughed and joked with a girlfriend – Naomi Campbell, and "I Kissed a Girl"'s Katy Perry also made the scene.
Madonna – who had spent the previous night partying for husband Guy Ritchie's birthday – showed no signs of fatigue as she aerobicized her way through super-charged renditions of "Vogue," "Into the Groove" and her newest hit, "Give It 2 Me."
