Alli Sims Signs Autographs?!?

No BritBrit, no problem.

While the popwreck was driving around town with some mystery dude, her trusty cousin assistant sidekick Alli Sims picked up the slack and set off a snapstorm of her own last night outside of Hyde Lounge in Hollywood. Way to ride them thar coattails, y'all!

Heading home after a night on the town with fellow exhausted Brit wrangler Sam Lufti, the aspiring songbird stopped to sign her very first autograph.

Is she, like ... a celeBRITy now?
