Lindsay Lohan and Paris Hilton's tumultuous relationship may be on the upswing. The two were supposedly seen at Michelle Trachtenberg's birthday party giggling together like young Japanese schoolgirls:

On Saturday night, the terrible twosome arrived arm-in-arm to Michelle Trachtenberg's 21st birthday party at Tao and spent the night signing autographs for fans and whispering to each other. Then the ditzy duo retired to the $25,000-a- night Sky Villa at the Palms - for a pillow fight, no doubt.

I'm a little suspicious of this story without pictures--preferably with the both of them dressed up in hilariously ironic costumes such as a short giraffe or a skinny hippo. Suspicions aside, I've still decided to honor this momentous reunion via haiku:

Both stay together

Next day, room looks like whore house

Not invited back
