NEW YORK: Perez Hilton says Lady Gaga’s behaviour towards him has left him full of ‘’sadness’’ and he doesn’t think they can repair their friendship.  The pair were once good friends but their relationship has broken down and descended into a full-blown feud after Gaga accused the gossip blogger of stalking her by looking at an apartment in the same New York apartment block she lives in.  Perez is disappointed about what has happened but is ready to move on.  During an appearance on ‘The Kyle & Jackie O Show’ on Australian station 2Day FM  she said: ‘’The deal is, that she really makes me sad, there’s a sadness.’’–XP
