Don’t look for Madonna and “Today” show cohost Matt Lauer to exchange Valentines this month. The Material Mom, who’s promoting her new movie “The Next Best Thing,” reportedly kept the morning hunk waiting for nearly four hours — and she still didn’t show — before he bagged the interview taping in a Manhattan hotel. “To hell with this,” Lauer was quoted as saying by the New York Post. Madonna spokesperson Liz Rosenberg told the paper that Madonna was simply backed up with a series of other interviews, including one with her pal Rosie O’Donnell, and was saving the “Today” Q&A for last because Madonna wanted to give Lauer the most time. That may still happen, says Rosenberg; Madonna sent Lauer “an enormous and beautiful” bouquet of flowers as an apology, said a “Today” rep. Lauer himself wouldn’t confirm a rescheduling, however. “I didn’t think it was unreasonable to leave,” he told the Post. “I had other things to do.” As for circulating rumors that Madonna is pregnant, Rosenberg denies those reports.
