Madonna's first concert in Britain in seven years drew some 9 million fans, who tuned in over the Internet.
Only about 2,800 people were able to see the concert in person Tuesday night. The fans crammed inside London's Brixton Academy for Madonna's performance featuring her latest album, "Music." The 42-year-old singer said she was warming up for a summer world tour.
During the show Madonna wore a T-shirt emblazoned with the name of her 3-month-old son, Rocco Ritchie, on the front. The back read "Lola," a nickname for her 3-year-old daughter, Lourdes.
