Janet Jackson and her boyfriend Jermaine Dupri have called it quits, according to Jermaine’s friends. A source told reporters today that the reason for their split had something to do with the fact that producer Jermaine had recently begun working with Janet on her music. The source said,

You shouldn’t mix business with pleasure. Janet felt their lives were too crossed and they should have kept things sepa­rate.

Their differing personalities are also being blamed for their break-up. Janet was reportedly shy and private throughout their relationship, while Jermaine was outgoing and open. Add to that, the fact that Janet had recently picked up some very heavy baggage - taking on the mommy role to her brother Michael’s three kids.

Janet and Jermaine first began dating about seven years ago, two years after Janet’s divorce from her husband Rene Elizondo.
