Lindsay Lohan and Samantha put on their matching leather jackets and headed to LAX last night. The pair were on their way to Scottsdale, AZ, for Samantha's gig at a club, only things got dramatic when a 38-year-old man tried to bypass security to get closer to Lindsay and ended up getting arrested for disorderly conduct. Fortunately, when interviewed by the police, LL and Sam said they hadn't even noticed the commotion. Samantha has a gig tomorrow night in Houston, so the pair will be leaving Arizona and for Texas. Earlier this week Lindsay blogged about watching Without a Trace late night together, but considering how much these two are on the move, I wouldn't be surprised if most of the screenings were en route from one place to the next.
