Madonna had to apologize to fans in Toronto last week after greeting them by saying, “Are you ready, Boston!” She’s currently out on the North American leg of her Celebration Tour. After playing two shows in Boston on January 8 and 9, the show moved north of the border to Toronto’s Scotiabank Arena for a couple of shows on January 11 and 12. At the second of the two, Madonna made the slip of the tongue, before correcting herself.
