Eminem is planning to reunite his rap group D12, three years after the death of friend and bandmate Proof.

The superstar was stunned by Proof's 2006 murder and recently revealed he sank into a deep depression as he battled to come to terms with the sudden loss of his best pal.

But now he's made his solo comeback, Eminem insists a D12 reunion is inevitable - because the group has such a tight bond.

Eminem says, "Me and the guys, we got a bond, it's special. It's like, as far as the future of D12, we're gonna be back in the studio soon."

The group reunited for a one-off performance last month to promote Eminem's new album Relapse.
