There are so many things that don't mix well with Lindsay Lohan these days (cocktail references excluded).
One has always been bras. Lindsay Lohan hates bras. That's one of the things we love about her. The other thing is apparently helicopters. Because Lindsay got so shaken (not stirred) by her helicopter transport down on her Brazilian pimping and partying before rehab mini tour that she didn't notice her boob fell out of her dress.
Now, I'll deny this in court if ever questioned in a criminal matter, but I pretty much know when my junk is hanging out bare outside my clothes. But Lindsay, some yaws, pitches, and rolls, and out comes the righty. If not for Lindsay's long locks, she would be fully and udderly exposed. Enjoy.
