Slash -- I LOVE Axl... (The Baby).

Rock-n-roll legend Slash has no love for ex-Guns N' Roses bandmate Axl Rose -- they have a 20-year feud and no one really remembers why -- but he still thinks Axl is a great name for a kid.

Slash -- sans trademark tophat and wearing a backward ballcap -- hit up The Sayers Club in Hollywood last week ... and had nothing but love for Fergie and Josh Duhamel's baby -- who they are rumored to have named after Axl Rose.

"I think it's really cool, I actually talked to [Fergie and Josh] yesterday, " Slash told us. "It's all good ... who am I to judge?"
