Slash Bans Ex-Wife Perla From Their Son's Band's Hollywood Gig

Slash is slamming the door on his ex-wife, Perla Ferrar ... blocking her from their son's huge Hollywood performance -- opening for Slash -- but it looks like she's totally ignoring the ban.

Sources close to Perla tell TMZ ... the Guns 'n Roses rocker banned her from attending the Tuesday night gig at the Hollywood Palladium -- 16-year-old London's band, Classless Act, will warm up the crowd before Slash takes the stage.
