Lindsay Lohan Shows Up During Lily Allen's Performance

Lily Allen decided to cover Britney Spears' "Womanizer" once again. This time, she was live, and Lily Allen performing the song isn't strange whatsoever. What is strange though, is Lindsay Lohan showing up out of nowhere to greet her. Wow, does Lindsay Lohan ever have time on her hands or what?

Lily Allen's performance is meh at best, but when Lindsay Lohan shows up (at about 3:35) and does some weird dance move, you really have to ask yourself... How coked up does one have to be to show up on stage during Lily Allen's performance and think it's cool? Only Lindsay Lohan can answer that, my friends, only Lindsay...
