Lohan suffers further drink relapse?

Lindsay Lohan has reportedly been captured on CCTV drinking vodka while out partying at a Washington DC nightclub.

The Mean Girls star checked into rehab three times last year following her arrest for two separate DUI incidents.

Reports that the 22-year-old has fallen off the wagon emerged seven months after a previous alleged relapse.

The footage is said to show Lohan in a dark corner of a club sneaking vodka and Red Bull into a glass before drinking its contents.

The actress is currently rumoured to be experiencing difficulties in her relationship with DJ Samantha Ronson.
