A creepy (read: damaged) fan on Twitter has been sending Christina Applegate's fiance death threats for swiping Christina out from under him. Even though they've probably never met.

The tweeter, who's obviously severely disturbed, has convinced himself (we're assuming it's a "him") that he had a romantic chance with Christina and that her betrothed, musician Martyn LeNoble, took her away. Perhaps this person is obsessed with the memory of Applegate's exquisite anchorwoman breasts?

The tweets began arriving on Sept. 20 and started with, “You stole [Christina] away from me. If not for you she would be mine.”

Okay, psychotic and a little weird, but not dangerous. Yet.

But then the missives continued with, “I will not accept this. I am going to kill you!!!!!!!!!”

Death by excessive punctuation seems to be the tweeter's chosen path of demise for LeNoble, but the threats got more violent as they continued, with most of them focused on exploding or caving in LeNoble's head.

"Be afraid, be very afraid!!” the tweeter warned. “You think this is a joke? I want to see how funny you think I am when I blow your f**king head off!!!”

Dude. We're sensing some animosity here.

Police went to the Twitter headquarters with a search warrant, but since the offending account has now been deleted, they're having trouble tracking down the deranged fan.

We're not FBI profilers or anything, but we suggest looking for a guy with a well-worn Kelly Bundy T-shirt and a keyboard with a broken exclamation point.
