Paris Hilton finds something about Lindsay Lohan very amusing, apparently.

In the ever-escalating feud between the two starlets, the lodging heiress cackled her way through a party both she and Lindsay attended in Malibu last weekend, bringing to mind another, more infamous, Lohan-directed Hilton giggle-fest.

Not long after she snickered her way through Brandon Davis’ “Firecrotch” tirade on the streets of Hollywood, Page Six reports that she “made it a point to whisper and laugh very loudly the entire time” at the Polaroid Beach House in Malibu last Saturday where Lohan was also partying with new beau Harry Morton – and where she also was seen getting cozy with the freshly-out-of-rehab Davis.

Lohan, as has been her wont in these situations, elected to stand down and slipped away with Morton to a back bedroom, where they couldn’t hear Paris’ shrill guffawing. And then, when Hilton walked past later on, one of Morton’s friends faked a kick to her bottom, according to a witness. No word on whether the oil heir Davis and Hard Rock empire heir Morton settled the feud with a duel on the beach.

Blohole did the right thing by not engaging in a battle with Prissy Hilton.
