According to recent reports, pop/R&B diva Janet Jackson and longtime boyfriend Jermaine Dupri are calling it quits after four years. The couple made headlines recently when pregnancy rumors hit the 'net.

Dupri denied the rumors and called out bloggers who've contributed to the speculation. But Jackson may have fueled the baby bump watch when she canceled tour dates in October due to a mystery illness.

Tabloids claim the pair have been at odds over Jackson's career and decided to go their separate ways." Janet and Jermaine finally hit a wall," an insider says. "They were fighting over his management of her career. In the end, she decided to make a break." Jackson and Dupri have yet to release a statement to confirm or deny the split.
