Perez Hilton and Lady Gaga's friendship well and truly broken

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.
