Lindsay Lohan leather airport smile

Oh how we've missed them!

Last night Lindsay and Ali Lohan were snapped arriving at LAX, and after that Lindsay went out to party! Jet lag what? This girl was born to do the nightlife scene, so is anyone surprised?

Lindsay went to the Grove with a mystery man to catch a movie, and after that she went to Trousdale around 12:30am. At 2:30am Lindsay snuck out the back door of the club, hopped in a black Ferrari and headed to the Chateau Marmont, and we're thinking she might still be awake at this point!

Will she EVER slow it down? And P.S. doesn't Ali totally look like her daddy in this shot?
