Eminem — Mum on Lil Wayne After Dinner in L.A.

Eminem made a rare public appearance this weekend — dining out at a popular L.A. restaurant … and it”s possible he”s in town to visit his friend Lil Wayne.

our sources shot footage of Em leaving Marino restaurant on Melrose by himself Friday night … covering his head with a hoodie.

But when we asked about Lil Wayne — who he”s rapped with on multiple songs including, “Forever” and “Drop the World” — it was clear, Mr. Mathers wasn”t in the mood to talk.

We broke the story … Wayne is in the ICU at an L.A. hospital after suffering multiple seizures last week.
