Kathy Sluck reveals her daughter and the Berzerk hitmaker see each other "all the time" and "get along better than ever".
Eminem is also reportedly building his daughter's mother a house close to his own home in MAComb, Michigan, so the family can spend more time together.
Sluck tells RadarOnline.com, "I think they might (get back together soon)."
And she's not the only one hoping for a reconciliation - Marie Hartter, the grandmother of Eminem's adopted daughter Whitney, adds,"They will probably grow old together one way or another, as much as he says he hates her in his music, he loves her that much too, I feel. I think it's kind of, like, throwing gas on the fire.
"I think they met very young, they were together a lot of years, I don't think she's ever been with anyone for as long as she's been with him."
The couple's on/off relationship has been marred by infidelities, legal issues and drug use and the rapper has referenced their troubled times in several of his songs.
Eminem and Kim have been together since they were teenagers. They welcomed their daughter, Hailie Jade, in 1995 and married in 1999. The couple divorced in 2001, but remarried in 2006. They divorced for the second time later that year.
