Lindsay Lohan spotted with mysterious white powder coming out of shoes

'Mean Girls' star Lindsay Lohan was recently pictured walking with mysterious puffs of white powder coming out of her shoes.

Lohan, 23, who was wearing a tiny black dress, did not seem to notice the powder puffing out of her shoes as she left a friend's house and walked along a Los Angeles street.

The actress' friends had revealed before the incident that she has been in a series of falls and struggled even to stay upright.

"In several 'mishaps' she has blamed her high-heeled shoes or paparazzi for pushing her. But just last week she fell over a cactus," the Sun quoted one as telling a US newspaper.

"If she doesn't get help soon, she's going to die," the friend added.
