Lindsay Lohan, Paris Hilton Fight in Public. Or Make Up. Or Somehow Interact.

It's not very clear at this point. But here's what we do know about two of The Gossip's favorites:

Following a party thrown by Us Weekly last night, Paris Hilton truly threw it down. She cleaned out the rolodex with invites, as those in attendance included: Pamela Anderson, Courtney Love, Jeremy Piven and Dave Navarro.

But the arrival of the night belonged to Lindsay Lohan.

Perez Hilton is reporting the two got into quite a yelling match in front of guests. Many overheard Paris telling Lindsay that she had never hit on Lindsay's boyfriend, Harry Morton. Reports also state that Kevin Connelly, the Entourage star diddling Nicky Hilton, slugged Brandon Davis in the face - twice!

TMZ contacted Paris' publicist, Elliot Mintz, about the report. His response?

"I was at the party, I remember Lindsay arriving and them having a lovely conversation by the pool. They seemed to have gotten along just fine and only polite words were exchanged."

Uh-oh. If Paris and Lindsay make up, what will be our go-to celebrity feud? Brangelina vs. Abject Poverty? Mel Gibson vs. Non-Catholics? Sean Preston vs. The Fashion Police?
