4. Janet Jackson and Jermaine Dupri

Janet Jackson and music producer Jermaine Dupri called it quits after seven years due to “mixing business with pleasure”.

“His friends are telling people it’s over,” according to an Us Weekly report in last July. Dupri, who was noticeably absent from Michael Jackson’s memorial on July 7, produced several of Janet Jackson’s recent tracks on her last two albums — which could have contributed to the split, according to the mag. Jackson was previously married to Rene Elizondo. They divorced in 2000.
