Lindsers and kid sis Ali were partying in the penthouse of her new NYC complex on Thursday night.
Lindsay reportedly stayed clean, drinking only water, smoking and dancing as Samantha Ronson ran the DJ booth. The two headed back to Lindsay's apartment around 10 pm.
Mom Dina Lohan showed up to say hi, but Lindsay nixed the cameras following Dina for her new reality TV show, so Dina only stayed for 20 minutes.
Good thinkin', Linds!
