Madonna Touring, Janet Returning

Madonna launches a summer tour in arenas (not, unfortunately, the smaller venues it was thought she might tackle), hitting LA May 29 and Madison Square Garden June 28-29. Her last tour was a smash hit that focused on the hits. This one -- awash in disco balls she says, will be all about the new CD and her big dance hits. Meanwhile, Janet Jackson -- presumably having lost some weight and refocused herself -- will release a single in May and an album around September. My how times flies: it's the 20th anniversary of Control.
