Hilton's Hot Rod Hits a High Note

Nightlife lover Paris Hilton sure knows how to make an annoying exit!

The airheaded heiress helped her manager Jason Moore celebrate his 35th birthday at Via Veneto in Santa Monica last night, and headed out to a familiar noise: her own car alarm!

Pitch imperfect Paris let her urban cricket cackle while a fan finagled her way into Hilton's private space for a quick pic. Oh snap(shot)!

Maybe the high octave howl was meant to tell her dog-of-the-day Jimi Hendrix that mamma's headin' home.
