Wow, these two really hate each other. Or so it seems.

Maybe they were really drunk and don't remember don't any of this later.

Lily Allen and Perez Hilton apparently went off at each other on Twitter.

Well, the blogger started it and then Allen responded and before you know it, everyone was eagerly watching the fur fly.

Quote from MTV:

It all started Thursday (August 27), when Hilton posted a photo of Allen on his Web site featuring the standard Perez treatment (lots of crude doodles) and the headline "Lily Allen + Motherhood = Disaster."

And then Allen seems to have replied with:

"I hate this man. Someone better watch themselves. And yes, that is a threat."

Then again, as the tabloids are pointing out, this might have been a low blow, even from Perez. They are recounting the time she had a miscarriage. Maybe this type of criticism is a bit uncalled for?

After all, shouldn't we be more worried about Amy Winehouse having a child right now?

Both of these celebrities are known for their sharp words ... and for picking fights. So I'm guessing we have not seen the last of the hissy fits between them.

Meanwhile, if you are keeping up to date on their little fight, you might like one of these weird t-shirts.

A designer called Queen of Suburbia based her latest creation on this ongoing tiff by making a t-shirt that simply says “Pap Me and I'll Pop You”.

Quote from  link:

"It struck me, that what I was reading was a very real example of how unsteady the relationships between the Paparazzi and Celebrity worlds are. Celebs need the "Paps" to help maintain their profile but at the same time bitterly resent the intrusive way they go about their jobs."
