HE may have a reputation for being the nicest guy in rock, but it turns out that there's at least one person who can turn DAVE GROHL nasty in a heartbeat.Apparently, one mention of the name PARIS HILTON sends the FOO FIGHTERS frontman utterly ballistic.Dave rages: "Paris is f***ing lame."And, warming to his theme, he continues: "She's more offensive to me than anything."She's a total, raging, disgusting, rich, lazy party slut. I pray that my daughter will not turn out like her."In an attempt to dispel Dave's claims Paris, erm, had another heavy night out partying in LA yesterday.Out until dawn, the heiress was again worse for wear - falling over leaving a club and even trying to climb over a gate to get into an unknown Beverley Hills property at 3am.She was also snapped earlier that night with another possible new love interest.Dave and Paris fell out in spectacular style after meeting in a restaurant years ago, when Dave claims that the pampered heiress put on "the full princess attitude with the nose in the air".
