You knew it was just a matter of time ... but Lindsay Lohan's accuser has already hooked up with Gloria Allred -- who smells a lawsuit?!??
It's unclear if Tiffany Mitchell has officially hired Allred as her attorney ... but the two were spotted together on the streets of New York City moments ago ... sporting a pair of million dollar smiles.
We broke the story ... Mitchell claims Lohan slugged her in the face at Avenue nightclub Wednesday night.
Stay tuned ... a news conference is probably on the way ...
