Express Yourself? Not so much.
took to the stage in Boston Wednesday – the same day she announced the demise of her seven-and-a-half year marriage
– but kept mum on her marital woes.
The 50-year-old singer tore through her athletic, two-hour set with her usual enthusiasm, as 30,000 fans at the TD Bank North Garden cheered her on.
The closest Madonna came to mentioning her soon-to-be-ex, Guy Ritchie, or her marriage came while introducing the song, "Miles Away." As she has in previous shows on her Sticky and Sweet Tour, she dedicated the song to the "emotionally retarded."
"You may know a few people like that," she said. "God knows I do."
Earlier this year, Madonna told Elle
magazine, that the song – which includes the line "When I'm gone you'll realize/That I'm the best thing that happened to you" – was inspired by her director husband.
"So many people have to deal with long-distance relationships," she told the magazine at the time. "It's not easy. You have to work hard to make it work."
Now, as the mother-of-three copes with her very public split, Madonna's fans are rallying around her.
"On the day she announces her divorce from a guy she really did love, all the die-hard fans are here to support her," said Boston concert-goer Peggy Rose. "[We] love her no matter what."
