LATEST: Rapper Eminem is making good on his promise to reunite with his ex-wife KIM MATHERS - the couple are planning to exchange vows again on 14 January (06).

American tabloid the Star has obtained the official wedding invitation which Eminem sent out to family and friends over Christmas (05) after revealing in a radio interview that he and his ex had reconciled.

In the invite, the STAN hitmaker states, "This day I will marry my best friend, the one I laugh with, live for, love."

He then invites his friends and family to attend the wedding of KIMBERLEY ANNE MATHERS and MARSHALL BRUCE MATHERS III (Eminem's real name) on 14 January at 5pm.

The couple have started living together with their daughter HAILIE, Kim's niece ALAINA and her daughter from a former relationship, WHITNEY, who Eminem has legally adopted.

Eminem wed Kim in 1999 when his career was beginning to take off but he filed for divorce just 14 months later. The couple finally divorced in 2001.

But the news of a reconciliation hasn't delighted everyone in Eminem's family - his outspoken grandmother BETTY KRESLIN is far from happy.

She says, "He needs to think twice about marrying her again, or at least get a pre-nup this time around."
