Crunch the numbers: Janet Jackson, 44, has announced a tour of 35 international dates on which she'll perform, at each show, her 35 No. 1 hits. It's all in support of a new greatest comp, "Number Ones."

She hits Chicago on March 7-8, playing two nights at the Chicago Theatre. That's an intimate venue for a very arena-level star.

"I will be as up close and personal as possible," Jackson said in today's press release announcing the tour. "These concerts are not about special effects. This is a love affair between me and those of you who have supported me and my work for all these years."

Tickets for the shows go on sale at 10 a.m. this Saturday (Jan. 15). They're $50-$200, available at the Chicago Theatre box office, all Ticketmaster outlets, online or by phone at (800) 745-3000.
