It can be extremely hard to watch what you're eating when you live with someone who stocks the fridge with all of your favorite unhealthy foods. Janet Jackson is finding this especially true -- her world tour begins in less than a month, and she has reportedly packed on some pounds this summer thanks to Jermaine Dupri's habit of filling her fridge with pizza, fried chicken, chocolate, and ice cream.

Janet's weight has always fluctuated -- back in 2006 she gained quite a bit of weight, but was able to lose it all in just four months. Earlier this year, Janet was looking fit and fabulous, and apparently she's hoping very much to get back to that point before her tour begins.

The singer might yo-yo diet, but it sounds like she's trying to drop the pounds healthily. She is now working with a nutritionist and chef and sticking to a 1700 calorie per day diet. I assume she's working out, too -- you know she has a great song for her playlist!
I think Janet looks gorgeous no matter what, and I have absolute sympathy for her situation. But, she's gotten really fit before, and I have no doubt she'll do it again, even with a fridge full of temptation.
