Johnny Rotten I've Got A Stalker ... Files Report After Alleged Trespassing, Phone Calls

Punk rock legend Johnny Rotten says he has an obsessed stalker in his midst who's been hitting him up on his phone and even coming to his house.

Law enforcement tells TMZ ... the Sex Pistols singer told L.A. County Sheriff's deputies a fan started harassing him last month by dropping letters in Johnny's mailbox -- and he says she picked up the pace, FAST.

Johnny said the woman took it to the next level by trespassing onto his Los Angeles-area property and strolling around his backyard. He says he even came face-to-face with her, and told her to scram.

That's when Johnny claims he started getting phone calls from her -- and that's when he decided to file a stalking report with the sheriff's department, which is now investigating.

He's Rotten, and Johnny says so is she.

Sex Pistol Off the Hook in Alleged Woman-Punch Lawsuit

Sex Pistols singer Johnny Rotten has settled a lawsuit for allegedly punching a female assistant in the face -- and we're told she's actually happy with the outcome ... who says punk is dead?

As we first reported, Rotten -- real name John Lydon -- got slapped with the lawsuit in 2008 when the assistant claimed Johnny called her a "f**king c*nt" and punched her in the face because his Ritz-Carlton hotel room wasn't up to snuff.

Now a judge has granted the assistant's request to dismiss the case -- and her lawyer, Keith Fink, tells us the matter "has been satisfactorily settled."

No word on exactly how "satisfactorily" ... since neither side will discuss money.
