Avril Hangs with Brit Hanger-On

Avril Lavigne showed up to Hyde last night with an interesting sidekick -- Britney Spears' former assistant/cousin, Alli Sims.


Alli's become quite the starf**ker lately; she was spotted at Paris Hilton's birthday party Saturday night as well -- ah, the Simsful life.
