Lindsay Lohan the diva

At a block-party carnival after the screening, Lohan explained her outburst.

"I was upset when I didn't hear my song (First) during the race scene, where I originally thought it would be," Lohan said while signing autographs. "I was like, 'Whoaaa,' because nobody stays to hear the song in the closing credits.

"So I ran out."

"I recorded it right before I got sick (from exhaustion) and went to the hospital. And then I shot the video for it and re-sprained my ankle. I pushed myself to get it done for the movie when I probably should have waited."
