Janet Jackson: What's Her Ailment?

I'm sure you've all heard that Janet Jackson has been canceling dates left and right on her Rock Witchu Tour. Speculation is running rampant - is she really sick? Or is her inability to fill a venue to blame? Well, add another rumor. Word is that Janet and her handlers are blaming her recent failures (in addition to her lackluster tour, her last 2 albums have flopped) on boyfriend, Jermain Dupree. Most recently it was reported that Dupree puked in Janet's lap on his birthday. Talk about adding insult to injury! Well, whatever the deal is - people paid good money for those tickets and if Janet isn't really sick she needs to make good on her end of the deal.
