Janet Jackson, 43, and her music-exec boyfriend Jermaine Dupri, 36, have reportedly broken up after nearly seven years of dating.
"His friends are telling people it's over, They have been moving in different directions for a while." a source told the new issue of Us Weekly.
A mutual friend revealed the reason for the split was due to different personalities and the conflicts arised when the couple worked together.
"You shouldn't mix business with pleasure, Janet felt their lives were too crossed and they should have kept things separate… Jermaine likes to be out there, mingling with everybody, and Janet's more shy."
Meanwhile, another insider said Janet is still deeply mourning the death of her big brother Michael Jackson.
"She's devastated. She's busy caring for Michael's kids. Janet's the family's backbone."
Dupri was noticeably absent from Michael's memorial service on July 7.
