Lindsay Lohan would have tried to pursue Robert Pattinson after a talk.
The vampire of Twilight is happily engaged with Kristen Stewart, but had a close encounter with Lindsay in one room in Los Angeles. It seems that Robert was already there when he got the actress who immediately approached him.
Some talk and then, Robert decides it's time to go home. At that moment without a second thought Lindsay tries to chase him. At least that's what I said photographers who witnessed this.
