Gwyneth, Kate and Nicole Get Into Groove for Madonna

Madonna's A-list pals had fans playing "Who's That Girl?" as they slipped into her London show on Thursday night, not long before the lights began to dim.

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."

And the open-air concert went off without a hitch, despite dire weather predictions in the notoriously soggy city. "I would like to thank God, all my friends," she said as the show wound down, "because it didn't f---ing rain!"
