Before Lindsay Lohan was arrested Thursday morning, she was actually having a pretty good night.

The Liz & Dick actress, 26, attended Justin Bieber's concert (with The Wanted as his opening act) at Madison Square Garden in NYC with her younger sister Ali Lohan, 18.

"She and Ali caused a scene with girls on the floor," a fellow concertgoer tells Us Weekly. "Everyone was taking pictures and they were rushed out."

But it sounded like Lohan enjoyed the run-in with fans. 

Prior to her arrest, the starlet tweeted (and since deleted), "I love all of my fans and Justin Bieber, The Wanted fans! Thank you so much for putting a smile on my face! Lots of love."

Sadly, Lohan's night didn't end with a smile on her face. The troubled actress was arrested and charged with assaulting a fellow clubgoer while out at NYC hotspot Avenue early Thursday morning after the concert.

"Lindsay was drinking a ton, not trying to hide it," an eyewitness told Us. "She was drinking Grey Goose and also champagne. The vodka bottle was right in front of her."

In addition to the third-degree misdemeanor assault charge she was booked for Thursday, Lohan was also charged with three misdemeanors the same day for lying to police about a June car crash in California.
