Here's hoping for a nice, calm celebration.
Sleeping, maybe? But that could cause another ordeal.
LiLo has had a roller-coaster year: receiving lawsuits; settling them; allegedly getting involved with club fights; making a guest appearance on Glee; and snagging the role of Elizabeth Taylor in a biopic.
We just can't tell which way her day is gonna go.
So how did the comebacking star celebrate? E! News has confirmed that LiLo partied down with a group of close friends early Sunday morning at David Arquette's new West Hollywood club, Bootsy Bellows.
The party was actually set to start at 10 p.m. Saturday, but guests didn't begin arriving until midnight. At around 2 a.m., the club brought out Sprinkles cupcakes and everyone sang "Happy Birthday."
Lohan was reportedly in "good spirits" and "was dancing around with her friends," an eyewitness tells E! News. "She seemed really happy."
No word yet if her Canyons costar James Deen was there. He seems like a good time.
