Madonna performed a 35-minute set in front of a 2,000-plus crowd at the Roseland Ballroom to celebrate the launch of her new album Hard Candy in New York April 30, 2008. At one point during the promotional concert, Madonna put down her young partner-in-song Justin Timberlake under her body against the wall when performing Four Minutes. Hooray! DM says Madonna is old enough to be Justin's mother. So?!
