Lindsay Lohan Ali, I Love You But I'm Bringing You Down

0215-lindsay-barhop-splash-01Lindsay Lohan spent Valentines day around the love of her life ... alcohol ... and her sister Ali Lohan.

Lilo went bar hopping with Ali Friday night in New York's East Village and both appeared to be date-free. Lindsay and Ali don't look drunk in the photos ... but the night was still young.

At least New York has plenty of cabs.
