Lindsay Lohan was seen drinking vodka on Thursday (17.05.07), it has been reported.
The actress, who entered rehab earlier this year to be treated for alcoholism, partied in New York without lover Calum Best last week, and has reportedly worried friends by hitting the bottle again.
A source told the New York Post newspaper: "Lindsay hit the Anchor Bar with two pals and was spotted drinking vodka straight from the bottle."
After leaving the Anchor Bar, Lindsay, 20, headed to the Sway nightclub and danced for an hour before returning to Anchor.
Lindsay Lohan then hopped on a private jet and flew back to Los Angeles at 3am.
