Steve Aoki (UCSB’99) and Jordy Masterson (next in the prodigy of DJ’ing masterson brothers), brought monday music to the upscale Sunset Tower Hotel (Home of Vanity Fair’s Oscar Party ‘09) to usher in Cinco de Mayo eve last night. (Mon 4 May) The party: LG and Teen.com’s “Haute and Bothered” Gossip Girl ‘esque series.

Two Lohan sisters  - Lindsay (23) and Ali (15) were the last celebs to arrive around 10:55 PM, Ali representing the only actual “teen” at the “teen.com” party.  Meanwhile, we waited patiently with America’s first crack at Is Vodka (pronouned ICE and given away liberally at the open bar) currently only available in LA and Las Vegas. I then took a 2nd-7th crack at it.  No glasses or drinking anywhere near the Lohan booth.

Other celebrities checking out the Teen.com show included Adam Rodriguez (CSI-NY), Chris Masterson,  Lisa Loeb, Samaire Armstrong, and Taryn Manning who hung with the wave-making celebrity interviewer Michelle Marie and considered leaving to go the Nylon/Myspace party over at the Roosevelt.
