Lindsay Lohan has apparently been caught on camera enjoying a alcoholic tipple or two.
A well-hidden security camera in Washington DC club appears to show the actress - who has been partying hard with DJ girlfriend Samantha Ronson in recent months - topping up her Red-Bull from a bottle of Grey Goose.

It's been suggested that the tape may have been tampered with - but you can decide for yourself below.
