The actress has reportedly levelled a very serious accusation at one of the guests who attended her friend's well-to-do nuptials.
According to Page Six, the 29-year-old told friends that was 'slipped a mickey' at Justin Etzin, businessman and ambassador of tourism for the Seychelles, and lingerie model Lana Zakocela's wedding in Florence, Italy last weekend.
The star seemed to have a few issues over the four day lavish event with the most serious being the night of the actual wedding.
A source told Page Six 'it was thing after the next' with the embattled star - who now lives in England and has struggled with addiction issues in the past.
The wedding insider said: 'Lindsay left the reception early.
'She'd gone back to her villa and was running around naked saying she was drugged.'
The Mean Girls star, according the source, also caused a fuss at the wedding - and not just because she wore a white dress.
The insider told the New York Post's social section, that despite the numerous pictures posted by Lindsay and the happy couple of each other, the star lost interest during the actual ceremony.
They said: 'Lindsay was painting her nails during the ceremony and looking at her phone.'
