Lindsay Lohan is really living it up at Art Basel in Miami.
The actress has been spotted at several star-studded soirées and was seen partying at the 1OAK pop-up at FDR Thursday night.
Insiders say that the Mean Girls star arrived at the lounge around 2:30 a.m. with a small group of friends.
Eyewitnesses at the nightclub tell E! News that LiLo was seen drinking from a champagne flute and being handed beverages throughout the night.
While it's unclear whether or not Lohan was drinking alcohol, she made no efforts to be a wallflower during her outing.
"She wasn't hiding it. She had a table in the back that had vodka and mixers on it. She didn't pour her own drinks, her friends would make them and hand them to her," a fellow party goer told us.
And despite only staying at the party for an hour, an eyewitness described her as "looking pretty rough."
By midday Friday, however, she had posted a few pictures of herself doing yoga in a one-piece bathing suit by the pool at her hotel in Miami.
Lohan completed 90 days of court-ordered rehab over the summer and immediately sat down with Oprah Winfrey to discuss her experience.
In August, Lohan opened up to the media mogul and admitted to being an addict.
When asked what her drug of choice was she said, "Alcohol. That, in the past, was a gateway to other things for me."
She also admitted to trying cocaine 10-15 times in her life even though she hated it, but said that the drug ""allowed me to drink more, I think that's why I did it."
The 27-year-old added that she "hates" being the example of a child-star-gone-wrong and told Oprah that she's just "tired. I've lived so many lifetimes at this point and it's not interesting to me anymore."
Lohan insisted "I'm different. I'm in a different headspace. I don't want those things that I wanted before."
