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”
